Sebastian Sayer opens a new window

Partner

I am a partner in Fox Williams’ financial services team. I specialise in contentious FS regulatory and white-collar matters, acting for both corporate and individual clients.”

Described in Chambers and Partners as a “tough litigator” with “exemplary approachability, articulacy and responsiveness”, Seb advises corporate and individual clients on contentious financial services regulatory and white-collar crime matters.  His clients include banks, investment firms, FinTechs, other financial services firms, and senior individuals working at those firms.

Seb has a specialism of advising in relation to investigations, whether those be conducted by law enforcement agencies or a regulator, as part of a public-facing inquiry, or carried out internally (such as by an employer).

He regularly advises clients on matters relating to the FCA’s Senior Managers and Certification Regime, such as non-financial misconduct issues, Conduct Rules, governance, and Senior Manager applications.

Seb often works with his colleagues in Fox Williams’ employment department, ensuring that clients simultaneously receive coordinated regulatory and employment law advice.

Seb is ranked in both Legal 500, and Chambers and Partners.

Prior to joining the firm, Seb worked in the Enforcement division of the FCA for five years.  Seb was a senior prosecutor, and carried out many high-profile investigations and prosecutions including multiple cases taken to trial at Southwark Crown Court. This included one of the FCA’s most high-profile insider dealing prosecutions, involving a compliance officer at a major Swiss investment bank.  He maintains strong links with colleagues from the regulator.  Seb is a barrister by background, having been called to the Bar in 2007 and practising in chambers (before the FCA) at Foundry Chambers.
