Investigations and White Collar Defence

Satnam Tumani leads our Investigations and White- Collar Defence practices.

Satnam's extensive practice spans from public company internal and external investigations (including those conducted by the UK Serious Fraud Office (SFO), the UK Financial Conduct Authority (FCA), the UK National Crime Agency (NCA), HM Revenue & Customs (HMRC), the UK Financial Reporting Council (FRC) and the UK Information Commissioner’s Office (ICO) to individual defence for senior executives.

He has significant experience advising companies facing UK public inquiries, as well as crisis management for senior executives and the boards of multinational companies, on sensitive legal or reputational issues.

Satnam has repeatedly been recognised and ranked in respect of white collar and investigations matters, including in the Legal 500  Hall of Fame.

Described as “dominant in the sector. He’s an outstanding leader who knows precisely what to do and how to do it. He is a genuinely intimidating presence for any opponent and achieves results like no one as a result.”

Clients commented that Satnam is “incredibly diligent and has a practical approach to issues”, and is “an excellent operator. Very strategic but also across the detail and client-centric”, and that he is “highly responsive”, detailed”, “very thoughtful, strategic and provides very high-quality advice”.

Satnam was previously recognised as part of a team that was “a leader amongst others and particularly suitable for the larger, thornier cases involving the Serious Fraud Office”…

…“among the very best of the best”, a “very well drilled team. They think of everything, in depth, many moves ahead of the opposition. If you want to win, this is the team to hire”, and having “outstanding experience and attention to detail”.

Before joining EMM in 2024, Satnam set up and led the White-Collar practice at the London offices of a prominent, global law firm (2012-2024).

Prior to that, he spent more than 17 years at the SFO where he directed, and worked on, some of the most complex criminal fraud and corruption matters in the UK, including international and domestic corruption, investment fraud, company fraud, insider dealing and market manipulation. Satnam was responsible for multi-jurisdictional cases involving the DOJ, SEC and a number of European and Asian prosecutors.

At the SFO, he advised on all aspects of the UK co-operating defendant regime, including the provision of immunities from prosecution and restricted use undertakings, and he was the lead point of contact on extradition and European Arrest Warrants.

Satnam‘s 17 years at the SFO included acting as the SFO’s Head of Bribery & Corruption, International Assistance and Sanctions Enforcement Divisions, where he supervised and oversaw approximately half of the SFO’s operational caseload.

He was actively involved in the development and implementation of SFO enforcement guidance, policy, strategy and related initiatives, including as a senior member of the SFO team dealing with the joint prosecution guidance for the UK Bribery Act and a member of the SFO Deferred Prosecutions Working Group.
