Brexit Group BRUSSELS/EU

Helping companies assess the issues, prepare for potential outcomes and identify actions to take in order to protect their interests in the wake of the UK's decision to leave the European Union.

The departure of the UK from the EU will have major consequences for many businesses and industry sectors. It is likely to remain at the top of many board room agendas as the UK and the remaining EU Member States clarify how the UK should withdraw and what the future relationship will be. As this process unfolds, we can help businesses adapt to the changing landscape and the risks and opportunities that may emerge. Our lawyers are ready to advise clients on all legal aspects related to Brexit, in particular on competition law, state aid, market access, energy, data protection, intellectual property and trade matters.

Lawyers in our Brexit Group bring more than 30 years of experience in all aspects of EU regulatory law. The team includes Claus-Dieter Ehlermann, the former Director-General of the European Commission's Legal Service and Director-General for Competition and a former member of the World Trade Organization's Appellate Body, and partners in Brussels, London, Frankfurt, Berlin and Washington DC.
