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.  

At Geradin Partners, he represents a wide variety of broadcasters, news publishers, app developers, gaming companies, e- commerce sellers and other companies on digital regulation in the UK, the EU and other jurisdictions. He has been involved in most of the CMA’s competition law investigations and market studies in the tech sector (and other sectors). Tom was the only private practice lawyer to be invited to give testimony to the Public Bill Committee of the UK Parliament during the passage of the Digital Markets, Competition and Consumers Bill.

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). At Geradin Partners, Tom handles clients’ multi-jurisdictional deals that require clearance in many different jurisdictions worldwide. He advised Veolia on the UK merger control aspects of its €13 billion acquisition of Suez, which was cleared with remedies at Phase 2.

Tom advises companies that are involved in market studies and market investigations, or under investigation for competition law and consumer law infringements, in a variety of sectors. He 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 pharmaceutical sector. 

He is a regular speaker at competition law conferences and appears frequently in the print and broadcast media, including the BBC Today programme, the Financial Times, Wall Street Journal, and Bloomberg TV. Earlier in his career, 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. 

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