About Alastair Chapman

Alastair is the managing partner of our UK antitrust, competition and trade practice.

Based in London, Alastair also spends time working in Brussels and has previously worked in Washington DC. He advises on all aspects of EU and UK competition law, and related commercial strategy.  He has extensive experience representing clients before EU and national regulators and courts, and regularly leads complex cross-border transactions and investigations.

Alastair has significant expertise working closely with clients across a broad range of sectors including consumer products and retail, financial services, private equity, food service, and technology media and telecoms. He is equally at home counselling in-house lawyers and executives, and coordinating large multi-national teams. His commercial approach to what can be a technical area of law means that he provides clear and pragmatic advice, and is conscious that the law is often only one part of the solution.

A frequent speaker at international conferences, Alastair is also co-author of the horizontal arrangements chapter of Bellamy and Child: European Union Law of Competition.
