Brian Altman KC’s main specialisms are public inquiries, fraud and bribery, corporate governance, compliance and regulatory work. A large part of his practice is advising prominent private and corporate clients, as well as the UK Government, on a wide range of high-profile and esoteric issues. His work involves both private prosecution and defence.

Brian’s clients have included high-net-worth individuals, foreign multinational corporations and UK PLCs and other organisations, as well as a Middle Eastern Royal Family. Typically, his instructions emanate from well-known and respected City solicitors, but also from in-house Counsel.

Brian has long and successful experience as leading counsel in the most serious, high-profile cases of murder and terrorism, and has headed and advised teams of lawyers and investigators countless times over several years.

In June 2013, Brian ended his highly successful tenure as Treasury Counsel at the Old Bailey, having been Treasury Counsel for some 16 years, the last two-and-a-half of which had been as First Senior Treasury Counsel.

Notable work

In May 2021, Brian was commissioned by the Director of the Serious Fraud Office ​to investigate and report into the collapse of the Serco trial of R v Woods and Marshall in April 2021. His report was published by the Serious Fraud Office on 21 July 2022.

The link to the Director’s statement and the Report and Annexes may be found at: https://www.sfo.gov.uk/2022/07/21/publication-of-brian-altman-qc-and-sir-david-calvert-smith-reviews/

In January 2017, Brian was appointed Lead Counsel to the Independent Inquiry into Child Sexual Abuse (IICSA) (to see The Times report of the appointment click here). Brian provided strategic and legal advice to the Chair and Panel on all aspects of the Inquiry, as well as overseeing the large counsel team. He appeared as Lead Counsel in a number of the Inquiry’s high-profile investigations. The final report was published in October 2022. See https://www.iicsa.org.uk/reports-recommendations/publications/inquiry/final-report

In the spring of 2021, Brian was appointed as Lead Counsel to the Brook House Inquiry, whose terms of reference were to examine the mistreatment of detained individuals at the Brook House Immigration Removal Centre in Gatwick, then run by G4S, which was exposed in a BBC Panorama programme in September 2017.   The Inquiry concluded in September 2023 with the publication of its report. See https://www.gov.uk/government/publications/brook-house-inquiry

Brian is representing the Secretary of State for Defence and the Ministry of Defence in the Independent Inquiry relating to Afghanistan established in December 2022.

He is also instructed on behalf of Boris Johnson, the former Prime Minister, in Module 2 of the Covid Inquiry.

During his time as Treasury Counsel, Brian advised on, and prosecuted, some of the best-known cases of the day such as the case of John Downey, alleged to be an IRA man guilty of the 1982 Hyde Park bombing, who had erroneously received a comfort letter indicating he was not wanted in the UK; the notorious abduction and murder of Milly Dowler and the killing of Amelie Delagrange and Marsha McDonnell and the attempted murder of Kate Sheedy; the so-called ‘Babes in the Woods’ murder case – the killing of 9 year old Karen Hadaway and Nicola Fellows in Brighton by Russell Bishop in 1986. In March 2020, Brian led for the prosecution in the first trial concerning the death of PC Andrew Harper who was dragged to his death by a car driven by three young men escaping from their theft of a quad bike. That trial had to be aborted due to Covid-19. Brian was unable to prosecute the retrial in June 2020. The three were convicted of PC Harper’s manslaughter.

In March 2021, Brian, leading Simon Baker KC, Jacqueline Carey KC, Charlotte Brewer and Helen Jones (all of 2 Bedford Row), instructed by Nick Vamos of Peters & Peters and Hannah Laming (then Peters & Peters, now at Squire Patton Boggs), appeared on behalf of Post Office Ltd in the Court of Appeal Criminal Division in relation to 42 cases referred by the Criminal Cases Review Commission (CCRC) in what was the largest conjoined appeal ever heard by the Court of Appeal Criminal Division (R v Hamilton & Others [2021] EWCA Crim 577. You can read the full judgment here.)

The appeals all related to individuals who had been prosecuted by the Royal Mail Group and post-2012 by Post Office Ltd between 2000 and 2013 relying on evidence from the Horizon accounting system which has since been found to suffer from bugs, errors and defects. None of the counsel team, nor Peters & Peters, had been involved in prosecuting any of the cases during this period, and were brought in to conduct a thorough review of the cases to ensure proper disclosure was made and to advise on and conduct the appeals. Leading a team of over 60 review counsel, the counsel team oversaw an enormous post-conviction disclosure review exercise (with over 4 million documents subjected to review and substantially over 300,000 pages of material disclosed) to enable the appellants to advance their appeals.

Following advice from the counsel team, the appeals of the 39 successful appellants had been conceded on grounds of limb one abuse of process (with four of those 39 appeals conceded on grounds of both limb one and limb two abuse of process). Only three of the 42 appeals were opposed on all grounds, and the Court of Appeal upheld all three of those convictions.


Over the years Brian has consistently been acknowledged to be ‘a leader in his field’ by both Chambers & Partners and the Legal 500. In 2007, Brian was nominated by Chambers & Partners as ‘Crime Junior of the Year’ and in 2011 as ‘Crime Silk of the Year’. In 2013, he was nominated by Legal 500 as ‘Crime Silk of the Year’ and in 2022 as ‘Public Inquiries Silk of the Year’. Brian was also selected by Lawyer Monthly as winner of the 2015 ‘White Collar Crime Barrister of the Year – UK’.

The Times has named Brian in its Law 100 list as one of the country’s 100 most influential lawyers. He was also listed by The London Evening Standard in the law section of the list of London’s 1000 most influential people for 2011, and in 2012 he was named by The London Evening Standard as one of London’s top three ‘Golden Legal Eagles’ in crime.

Brian was also featured in The Times on 17 December 2020 as their Lawyer of the Week for his work as Lead Counsel to the Independent Inquiry into Child Sexual Abuse. See The Times.

Media and Select Committees

On 12 February 2024, Brian gave evidence alongside Sir John Saunders (Chair of the Manchester Arena Inquiry) and Kate Eves (Chair of the Brook House Inquiry) in the first evidence session of the House of Lords Select Committee looking into statutory inquiries, following on from the House of Lords’ Committee’s 2014 report on its post-legislative scrutiny of the Inquiries Act 2005.  Watch here: Parliamentlive.tv – Statutory Inquiries Committee

Brian was interviewed on Times Radio about public inquiries on 8 December by Ruth Davidson and on 10 December by Calum Macdonald.

The interview with Ruth Davidson is available on the following link (between 53.43 and 59.45): https://www.thetimes.co.uk/radio/show/20231208-17909/2023-12-08 and the interview with Calum Macdonald is available on the following link (between 02.48.10 and 02.55.52): https://www.thetimes.co.uk/radio/show/20231210-15971/2023-12-10

On 19 October 2022, Brian appeared before the Justice Committee in Parliament to give evidence about the report into the collapse of Serco trial of R v Woods and Marshall in April 2021. He appeared with Sir David Calvert-Smith (former DPP and High Court Judge) and Anthony Rogers (His Majesty’s Inspector of the Crown Prosecution Service) in relation to their report into the SFO’s mishandling of the Unaoil case. Watch here.

The case of Ash-Smith (an historic murder of a 16-year-old schoolgirl in which Brian successfully led for the prosecution) was one of two historic cases featured in Episode 3 of the BBC4 documentary series ‘The Prosecutors’ in which cameras were allowed into court buildings for the first time. The programme in which Brian was interviewed followed milestones in the preparation and prosecution of the case to its successful conclusion. See BBC iPlayer: the prosecutors.

Brian also featured in the 2019 BBC2 documentary ‘The Babes in the Wood Murders: The Prosecutors’ about the successful quashing of Russell Bishop’s acquittal in 1987 for the murder of two 9-year-old Brighton girls in 1986 and his retrial and conviction at the Old Bailey in 2018 in which Brian led for the prosecution. See The Times.

Media agencies frequently ask Brian for his opinion and input on current legal affairs, and he has been quoted and mentioned in many media articles. In a Channel 4 News online article by Patrick Worrall ‘Why is there no courtroom drama like the real thing’, dealing with the issue of cameras in the courtroom, Patrick wrote:

“Court reporters sit around and argue over top prosecutors the way that fight fans talk about boxers. Who’s the best, pound-for-pound? We all had our favourites. Mine was Brian Altman QC, vanquisher of Milly Dowler’s repulsive killer Levi Bellfield, among others. Mr Altman is an expert cross-examiner, breaking down the hardest of the hard men with patient, remorseless logic, trapping them with their own lies.” See Channel 4.

Brian has been interviewed by Clive Coleman, the former BBC legal affairs correspondent, for the Radio 4 Today programme broadcast on 4 April 2013 about the end of his tenure as First Senior Treasury Counsel and the workings of the Treasury Counsel system. See BBC News.

He has been quoted in several articles and often gives talks and seminars to legal professionals on practical and current legal issues.


Practice Areas

Public Inquiries

In January 2023, Brian was appointed to the team of counsel representing the Secretary of State for Defence and the Ministry of Defence in the Independent Inquiry relating to Afghanistan, established by the Secretary of State in December 2022. The Inquiry has been set up to examine and report on allegations of unlawful killings by British Army personnel in Afghanistan between 2010 and 2013, as well as the adequacy of investigations by the Service Police and alleged cover-up.

Brian has been instructed on behalf of Boris Johnson, the former Prime Minister, in Module 2 of the Covid Inquiry.

In January 2017, Brian was appointed Lead Counsel to the Independent Inquiry into Child Sexual Abuse (IICSA) (to see The Times report of the appointment click here). Brian provided strategic and legal advice to the Chair and Panel on all aspects of the Inquiry, as well as overseeing the large counsel team. Brian was Lead Counsel in the Inquiry’s high-profile investigations into Cambridge House, Knowl View and Rochdale, Allegations of Child Sexual Abuse linked to Westminster, The Roman Catholic Church, Institutional Responses to Allegations of Child Sexual Abuse involving the late Lord Janner of Braunstone QC and Effective Leadership of Child Protection.

IICSA was set up by the then Home Secretary (the former Prime Minister, Theresa May) in 2015 to investigate institutional responses into allegations of child sexual abuse made against State and non-State institutions in England and Wales. The Inquiry was one of the highest profile and largest statutory inquiries ever to be established by the Government and lasted in excess of seven years.

The Inquiry ended in 2022 when it published its final report on October 2022. The Inquiry has attracted a large amount of domestic and international publicity and continues to do so. See https://www.iicsa.org.uk/reports-recommendations/publications/inquiry/final-report 

In the spring of 2021, Brian was appointed as Lead Counsel to the Brook House Inquiry, whose terms of reference are to examine the mistreatment of detained individuals at the Brook House Immigration Removal Centre in Gatwick, then run by G4S, which was exposed in a BBC Panorama programme in September 2017.  The Inquiry concluded in September 2023 with the publication of its report.

Brian has prosecuted and advised the Crown Prosecution Service (“CPS”) and the Attorney General in many serious cased both as Treasury Counsel and since involving:

  • Advising solicitors in Singapore on behalf of a client charged with serious drugs offences in relation to trial and appeal proceedings taking place in Singapore
  • Advising Police Scotland on a highly sensitive enquiry arising out of the RUC shooting of two men in a hayshed in Northern Ireland in the 1980s
  • Murder, manslaughter
  • Corporate manslaughter
  • Breaches of the Health & Safety at Work Act 1974
  • Medical manslaughter
  • Police misconduct
  • War crimes
  • Official secrets and terrorism

Brian’s defence work is highly regarded. He was instructed privately by David Sonn of Sonn Macmillan Walker to represent a businessman, RF, at Snaresbrook Crown Court in September and October 2015. RF was accused of a large-scale drugs conspiracy. RF was acquitted following successful arguments regarding the admissibility of evidence which led to RF’s discharge on one of two counts he faced on the indictment, and he was finally discharged on the remaining count following a successful submission of no case at the close of the prosecution case.

In 2015, Brian was instructed privately by Ian Kelcey of Kelcey & Hall of Bristol to represent LW, one of four serving police officers, accused of misconduct in public office arising from a high profile murder case in Bristol in July 2013. Brian’s client was acquitted by the jury unanimously after a seven week trial at Bristol Crown Court which ended just before Christmas 2015.

In June 2017, Brian, who was instructed privately by Ian Kelcey of Kelcey & Hall of Bristol, secured the acquittal of GD, a former senior police chief in Avon & Somerset, who was accused of sexually assaulting women on cross country trains in the west country. GD had been accused by 3 women of 5 sexual assaults, but, following a 5 day trial at Bristol Crown Court, the jury acquitted GD of all the charges.

He is regularly instructed by the Crown Prosecution Service Counter Terrorism Division to prosecute terrorism offences including, most recently, those arising from the conflict in Syria, and by Complex Casework Units of the Crown Prosecution Service in a variety of high profile, difficult, and often historic, homicide cases.

Notable crime cases

R v GD

Brian acted for a former Chief Superintendent who was accused of a series of sexual assaults on women on trains in the west country. Following a trial in June at Bristol Crown Court, GD was acquitted of all charges.

R v AB

A multimillion pound money laundering case where Brian led for the main defendant. Despite the defendant pleading guilty to most of the charges only just before trial, and in spite of the amount said to have been laundered, Brian was able to secure a non-custodial sentence for AB.

R v LW

A high profile case in which the prosecution alleged that three police officers and one PCSO had misconducted themselves in public office in July 2013 in Bristol in relation to their dealings with a man called Bijan Ebrahimi. Brian represented one of the officers, LW, who it was alleged had failed to deal properly with Ebrahimi’s 999 call one evening in which he alleged that his neighbour, Lee James, had assaulted him in his home and had accused him (wrongly) of being a paedophile. It was said also that LW had failed to deal with Lee James’ behaviour at the scene, in particular James’s threats to kill Ebrahimi. Thus the prosecution alleged against LW that she had failed to arrest Lee James, or deal adequately with his behaviour, and that she had failed to investigate Ebrahimi’s complaint all due to her alleged antipathy towards him. LW faced a further allegation relating to a separate occasion when she had refused to speak to Ebrahimi when he had tried calling her when she was on other duties. Within an hour Ebrahimi was murdered by Lee James with an accomplice offering him assistance. LW was acquitted by the jury unanimously after a seven week trial at Bristol Crown Court.

R v Khalid Ali

Khalid Ali disappeared from London in 2011 and found his way to Afghanistan where he joined the insurgency, becoming a bomb-maker for the Taliban and the affiliated terror organisation, Al Qaeda. Ali returned to the UK in 2016 and in the following months began plotting to kill a policeman, military person or a politician in the Whitehall area which he had reconnoitered on two occasions before making his way to the area on 27 April 2017 armed with three knives in order to carry out his intentions. The plan was thwarted by armed police who intercepted Ali as he crossed Parliament Street. In later interviews with the police, Ali admitted to having been a Taliban bomb-maker and to having detonated over 300 IEDs to cause explosions. He freely admitted to being a trained Taliban fighter and a mujahid. He said he had returned to deliver a ‘message’ to the decision-makers in the UK. He said he had pledged his allegiance to successive leaders of the Taliban and to the leader of Al Qaeda. He resiled from this account at trial, claiming he had been captured by the Taliban or their affiliates and forced under threat of execution to make IEDs. He said that on 27 April 2017 he had only been carrying knives into town for his own protection and had not planned to carry out any acts of terrorism. The jury saw through his account and convicted him unanimously of making explosive substances and preparation of acts of terrorism.

R v Hassane, Majeed, Hamlett & Cuffy

This was the first prosecution of a major Islamic State-influenced plot to kill in the UK. The terror plot was successfully disrupted by the Security Services and police in late September and October 2014 with the arrests of several individuals. Hassane and Majeed plotted to kill servicemen or policemen in drive-by style shootings with a firearm with which they had been supplied by Hamlett and Cuffy. The plot was directed and funded from abroad, most likely from Syria, and while Hassane, who in July 2014 had pledged his allegiance to Islamic State, led the plot chiefly from Sudan where he was studying medicine, Majeed who had been studying physics in London acquired the gun from Hamlett and he was tasked to arrange for an untraceable moped and a lock-up, while engaging in secret communications with his controllers abroad on a laptop. The plot received further impetus in late September 2014 when the official spokesman for Islamic State issued a fatwa to extremists in the West to kill.

R v Khawaja, Bhatti & Ali

In this case Khawaja went to Syria in 2014 to join with Rayat al Tawheed, and IS-related jihadist insurgent force in Syria, where he received weapons training with a view to fighting. He returned to the UK after Rayat al Tawheed put out a false story on social media that Khawaja had been killed in battle in order to provide cover for his secret return. His cousin Bhatti assisted him to get back into the UK, and Ali had helped fund his journey into Syria. All pleaded guilty to a variety of terrorism offences.

R v Sarwar & Ahmed

Two young men pleading guilty to engaging in conduct in preparation of terrorism, having been in and returned from Syria after five months with Al Nusra, an Al Qaeda-affiliated group, fighting Assad’s regime.

R v Begg

Former Guantanamo detainee charged with terrorism offences but dropped in light of material undermining the case.

R v Downey

‘On the run’ IRA man accused of 1982 Hyde Park bombing but not prosecutable having erroneously received a letter of assurance from the government in 2007 that he was not wanted in the UK.

R v Naseer, Khalid & Ali

Convictions of Birmingham terror bomb plotters at Woolwich Crown Court in February 2013 following a 5 month trial.

R v Lewington

Conviction of white supremacist for offences under the Terrorism Acts 2000 and 2006 and the Explosive Substances Act 1883.

R v Boukhezer

Terrorism Act offences arising from the raid on Finsbury Park mosque.

Operation Odin

International plot to bomb the Christmas market in Strasbourg.

R v Rivas & Others

News of the World scoop about a plot to kidnap Victoria Beckham.

Murder & Manslaughter

Brian has advised in and prosecuted some of the biggest homicide cases of the day and continues to do so. He has been instructed in several defence homicide cases.

Notable murder & manslaughter cases

R v Long, Bowers & Cole

Brian led for the prosecution in the high-profile case concerning the untimely death of PC Andrew Harper, a Thames Valley Police Officer who was killed in the line of duty in August 2019 in Berkshire. The three defendants had been involved in the theft locally of a quad bike and were fleeing in their car when PC Harper tried courageously to apprehend them. Caught by his ankles in a tow rope tied to the boot of their car, he was dragged to his death by the car for over a mile. The first trial which Brian prosecuted in March 2020 was aborted in the third week due to the loss of jurors owing to the impact of Covid-19. Brian was unable to prosecute the retrial in June 2020 because of other pre-existing professional commitments. All three defendants were convicted of PC Harper’s manslaughter.

R v Russell Bishop

Brian led for the prosecution in this notorious murder case from 1986. Both victims were 9-year-old girls. Bishop led the little girls into woods within half a mile of their Brighton homes and strangled them to death and sexually assaulted them. He was charged and tried with the murders at Lewes Crown Court but acquitted in December 1987. However, in 1990 he went on to abduct, attempt to murder and sexually assault a 7-year-old girl for which he was convicted and sentenced to life imprisonment. In the meantime, the murder case remained open and was reviewed over the decades. Eventually new scientific evidence led to the quashing of the acquittals by the Court of Appeal in December 2017 and the ordering of a new trial. In October 2018, the new trial began, and in December 2018 (in fact on the very same day 31 years after his acquittals) Bishop was convicted of the murders and sentenced to life imprisonment with a minimum term of 36 years. The case is the oldest to be tried under the double jeopardy rule.

R v Hampton

This was the high profile case of the murder and sexual assault of 17 year old Melanie Road in Bath in 1984. The prosecution case was that she had been stabbed to death and sexually assaulted in a residential street as she returned home from a night out. A DNA sample provided by the defendant’s older daughter in 2014 following her arrest for a minor matter provided a familial match to DNA from the crime scene. The defendant voluntarily provided an elimination sample which led to his eventual arrest and charge. The defendant pleaded guilty to Melanie Road’s murder at Bristol Crown Court on 9th May 2016 and was sentenced to life imprisonment with a minimum term of 22 years. Brian was instructed to advise and represent the defendant by Kelcey & Hall Solicitors of Bristol.

R v SW

High profile case of 15 year old girl of previous good character accused of secondary participation in murder by the beating of a man on the street with an older youth. W’s erstwhile best friend who had been present at the scene gave evidence against her of direct participation in the attack and of filming the event on her phone, and another young witness alleged she had later confessed to it, despite which W was acquitted by the jury within an hour.

R v Collins

The defendant was one of three young men accused of involvement in a revenge knife murder following a gun attack on the home of a co-defendant. The defendant was convicted following a trial at the Old Bailey in 2014. The 24 year minimum term of his life sentence was later reduced to 22 years on appeal to the Court of Appeal.

R v Ash-Smith

Historic murder of 16 year old Claire Tiltman who was savagely stabbed to death in a dark alley in Greenhithe, Kent, in January 1993.

R v Ekaireb

Business Crime

While Brian’s main area of practice is in serious crime, his practice sees him regularly advising both private and corporate clients across a wide and esoteric range of commercial activities and issues, including on private prosecutions.

In addition to significant high net worth individuals, and household name corporations, Brian advised the Competition & Markets Authority (formerly the Office of Fair Trading) over several years in a high-profile UK-wide cartel investigation involving the construction industry, which concluded with the sentencing in September 2017 of Barry Cooper who had pleaded guilty to a cartel offence.

Brian has also advised the SFO in major blockbuster cases, and the FCA on insider dealing, and over the years he has defended, and advised, in large-scale fraud (such as the high profile Butte Mining PLC and Brent Walker frauds) including mortgage and tax fraud, insider dealing and other serious fraud and corruption cases.

In May 2021, Brian was commissioned by the Director of the Serious Fraud Office to investigate and report into the collapse of the Serco trial of R v Woods and Marshall in April 2021. His report was published by the Serious Fraud Office in July 2022. See Publication of Brian Altman QC and Sir David Calvert-Smith reviews – Serious Fraud Office (sfo.gov.uk)

On 19 October 2022, Brian appeared before the Justice Committee in Parliament to give evidence about the report. He appeared with Sir David Calvert-Smith (former DPP and High Court Judge) and Anthony Rogers (His Majesty’s Inspector of the Crown Prosecution Service) in relation to their report into the SFO’s mishandling of the Unaoil case.
