Lewis Power KC is a formidable advocate who has established a reputation as a leading practitioner both domestically and internationally. In February 2022, Lewis was featured as “Lawyer of the Week” in The Times, and has been described in the media as “being in the Top Ten List of barristers in the UK”.
Recently, Lewis received national recognition for his successful efforts in overturning the conviction of a young woman accused of lying in a gang rape case before the Cyprus Supreme Court. Lewis specialises in complex and heavyweight criminal cases, including murder, criminal fraud, money laundering, bribery and corruption, offshore and international, serious sex crimes, terrorism and war crimes. Notably he successfully defended in the London Bombing trials at the Old Bailey in London, and was lead Counsel in the private prosecution of the current UK Prime Minister, Boris Johnson.
Lewis has successfully appeared for the defence in a number of high profile murder cases achieving a string of acquittals. Clients consistently comment on Lewis’ strategic and tactical acumen developed through nearly 30 years of trial advocacy, latterly in international or trans-national cases, including Cyprus, India, USA, the Balkans, the United Arab Emirates and Ireland. Lewis also regularly acts as a guest lecturer and speaker across the globe, regularly appearing on National TV and in a variety of documentaries giving his insight into topical legal issues.
In 2023, Lewis has been instructed in perhaps the most high profile criminal case in the UK, the fugitive and missing baby case of Constance Marten. Lewis also successfully acted for Alan Waller who brought an action against the BBC for defamation in the Princess Diana case, arising from the fabrication of bank statements by the BBC’s former journalist. Martin Bashir. Lewis also acted in the first case of its kind this year R v Sarah Lloyd Jones, involving the gross negligence manslaughter of a 16 year child, the neglect being diet related which was the first case televised in Wales regarding sentence. Lewis also is to receive a Honorary Degree of Doctor of Law this year in recognition of his significant contribution to the legal profession both domestically and internationally.
Lewis is recognised as a leading Kings Counsel by both Chambers UK and the Legal 500, commenting in particular on his renowned strength in cross-examination: “The epitome of a modern silk. He is approachable, naturally charming and engaging, with a work ethic that is second to none. His cross-examination is effortless and even in the most hopeless of cases, he fights tenaciously for the client and leaves no avenue unconsidered.” He is referred to as “an unrivalled cross-examiner” where his style is said to be “nothing short of brilliant”.
