Our specialist Competition & Antitrust team helps clients identify and deal with the risks associated with competition law, helping to avoid issues upfront and advising on investigations when they occur.


gunnercooke’s Competition & Antitrust team acts for companies in antitrust proceedings before courts, competition authorities and sectoral regulators in the UK, the EU and other jurisdictions. They have extensive experience in behavioural cases, merger control reviews, market studies and investigations, competition litigation, and complex compliance matters.

We act for defendants and complainants on contentious issues worldwide. We also advise on a wide range of other antitrust matters, including commercial agreements, pricing (especially by companies with strong market positions), distribution, licensing and supply agreements. We also help clients to establish and maintain compliance programmes.
