Hugo Keith KC is recognised as one of the legal profession’s leading King’s Counsel. In the current Chambers and Partners Guide to the UK Bar he is ranked in no less than seven categories: ‘Star’ ranked in Extradition and in Financial Crime; Band 1 in Financial Crime: Corporates and Inquests & Inquiries; Band 2 in Sanctions and Administrative & Public Law; and Band 3 in Proceeds of Crime & Asset Forfeiture. He is Joint Head of Chambers at Three Raymond Buildings.

He was a member of the ‘A’ Panel of civil Treasury Counsel for 8 years, during which time he regularly appeared on matters of public and criminal law both on behalf of Government departments and as amicus curiae before the High Court, Court of Appeal and House of Lords. He has appeared in 15 cases before the House of Lords/Supreme Court. He won the Chambers and Partners award for criminal barrister of the year 2008, and took silk in 2009.

As well as his regular appearances in the High Court and Supreme Court, he has been instructed in some of the most high profile cases of recent years. He represented Princess Anne when she was prosecuted, and represented The Queen in the Inquest into the death of Diana, Princess of Wales. He appeared on behalf of Malcolm Calvert in the Cazenove inside dealing case. He was appointed leading Counsel to the Inquests into the London Bombings of 7 July 2005 and, subsequently, appeared in the Leveson Inquiry on behalf of Rebekah Brooks. He appeared in the Mark Duggan, Alexander Litvinenko and Westminster inquests, and represented the Home Secretary in the El-Gizouli judicial review (concerning one of the ‘Jihadi Beatles‘) and the Electoral Commission in its proceedings against Leave.EU. He appeared on behalf of Airbus in the largest Deferred Prosecution Agreement yet concluded, and advised Chelsea FC in relation to aspects of its sale in May 2022.

Hugo is instructed by companies, high net-worth individuals, and politically exposed persons relating to all aspects of extradition (including advising on Interpol and on international restraint), international criminal/corporate liability, and criminal judicial review. His extradition and MLA cases include the leading cases of Berezovsky, US v Bermingham (the Natwest Three), Abu Hamza, Gary McKinnon, Shrien Dewani and Hamdi Ipek. He has successfully defended clients in every extradition case in which he has been instructed against the Russian State.

He is also a recognised specialist on sanctions law, and particularly since February 2022, has been consulted by many of London’s leading law firms and by a significant number of global businessmen, industrialists and corporations in relation to their sanctions exposure. He is acting on behalf of a number of sanctioned individuals in connection with their challenges to the UK Government.

In the field of financial and international crime, he advised on the UK’s first Deferred Prosecution Agreement (Standard Bank Plc) and appeared in two of the most recent DPAs (Guralp Systems Limited and Airbus). He has been involved on behalf of individuals or corporate bodies in a large number of the SFO’s highest profile investigations of recent years: LIBOR, EURIBOR, FOREX, Alstom, Autonomy, Rolls Royce, TescoUnaoil, ENRC and Glencore.

He is an expert on search and seizure, restraint and confiscation, and appeared in the leading cases of Rawlinson & Hunter Trustees and Others (search warrants), Golfrate (search warrant), and Malabu Oil and Gas (international MLA restraint).  He is also a renowned appellate advocate, and has appeared in a significant number of leading criminal cases in the UK higher courts. He has appeared twice in the Hong Kong Court of Final Appeal, including in the appeal concerning the former Chief Secretary of Hong Kong.

He is currently Lead Counsel to the UK Public Inquiry into the Covid-19 pandemic.

I, Hugo Keith KC, am a data controller and can be contacted at 3 Raymond Buildings, Gray’s Inn, London WC1R 5BH or by telephone on 020 7400 6400 or by email at hugo.keith@3rblaw.com. My Data Protection Policy can be found below.

All personal data that I process is for the purposes of providing legal services, conducting conflict-checks, marketing, defending potential complaints, legal proceedings or fee disputes, keeping anti-money laundering records, training other barristers and pupils and when providing work-shadowing opportunities, and/or exercising a right to a lien. The types of data I process vary upon the nature of the legal matter in relation to which I am engaged to advise, but can include names, contact details, biographic details and ‘special category personal data’ (such as details of racial or ethnic origin, political opinions, religious or philosophical beliefs, health, sex life and criminal convictions and proceedings).

Depending upon the circumstances of the case, the legal bases upon which I process personal data are (i) the performance of a contract to which the data subject is a party or in order to take steps at the request of the data subject prior to entering into a contract, (ii) the processing is necessary to comply with legal obligations to which I am subject, or (iii) the processing is necessary for the legitimate interests set out above, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subjects which require protection of personal data, in particular where the data subject is a child. When I rely on (iii) legitimate interests, my ‘Legitimate Interests Assessment’ can be found here. When I process data which has not be obtained directly from the data subject (e.g. personal data contained in evidential materials), it will have been supplied to me as part of my instructions in circumstances covered by legal professional privilege.

Depending upon the circumstances of the case, I may share the personal data with:

  1. my Chambers, which supplies professional and administrative support to my practice;
  2. Courts and other tribunals to whom documents are presented;
  3. my lay and professional clients;
  4. potential witnesses, in particular experts, and friends or family of the data subject;
  5. solicitors, barristers, pupils, mini pupils and other legal representatives;
  6. ombudsmen and regulatory authorities;
  7. current, past or prospective employers;
  8. education and examining bodies;
  9. business associates, professional advisers and trade bodies.

I normally retain personal data for no longer than 15 years after my involvement in the particular matter or case has come to an end, or as otherwise required by law. Many of the matters in which I have advised or acted give rise to proceedings long after my own involvement has ended, and the retention of data is particularly required for the purposes of conflict checks, further proceedings and AML checks.

I do not intend to transfer data to any country which is not either within the European Union, ‘white listed’ by the EU or otherwise permitted by EU law (e.g. to the USA under the provisions of the ‘Privacy Shield’).

Under the GDPR, data subjects whose personal data I process have the right to request from me access to, and rectification or erasure of, their personal data, the right to the restriction of processing concerning them, the right to object to processing as well as the right to data portability. Data subjects also have the right to lodge a complaint with the Information Commissioner’s Office (ico.org.uk).

In cases where there is a contract between me and the data subject, the provision of personal data is a contractual requirement and the data subject is obliged to provide the personal data in order that I can supply legal services. A failure to provide such data may mean that I will not be able to provide the legal services.
