Tom is a partner at Geradin Partners, having previously been Legal Director at the UK’s Competition and Markets Authority (CMA).

Tom led the legal team on the Digital Markets Taskforce, set up by the UK Government to advise it on the new regulatory regime for ‘digital gatekeepers’ such as Google, Apple, Facebook and Amazon.  He also directed the CMA’s influential digital advertising market study, the CMA’s work on setting up the Digital Markets Unit, and its antitrust enforcement cases in the tech sector.  

Tom was previously Director of Mergers at the CMA, responsible for the delivery of the CMA’s phase 1 mergers portfolio and liaising with the European Commission. He also guided many of the CMA’s most high-profile phase 2 merger cases such as Sainsbury’s/Asda (groceries), Illumina/PacBio (genome sequencing) and BT/EE (telecoms).

Outside the tech sector, Tom has significant experience in the banking sector, having led the team that implemented the UK’s Open Banking regulations, which came out of the CMA’s retail banking market investigation.  He has worked on several abuse of dominance cases in the pharma sector.

Before joining the CMA, Tom advised companies on UK and EU competition law at the international law firm, Hogan Lovells.  He spent time on secondment to the major broadcaster, ITV plc, and the UK’s Office of Fair Trading.  He is a regular speaker at competition law conferences.

Outside of work, Tom is on the Board of Trustees of Citizens Advice Southwark, a charity providing free confidential advice on issues such as debt, housing, benefits and immigration.
