Competition law is increasingly complex, important and international. Our experienced and highly rated 20 strong team of competition specialists can help you:

• ensure that your transactions and conduct comply with competition law
• identify and obtain the merger control clearances required for your transactions
• use competition law to help achieve your commercial objectives
• obtain compensation if you have lost out because of infringements by others.

Our UK-based competition lawyers work as part of a global practice which includes more than 100 competition and antitrust specialists working across 10 EU member states, alongside other competition experts in Africa, Asia, Australasia, Canada, Central and Eastern Europe, Latin America, Turkey, and the US.

Whether you are a business, regulator or government, you can benefit from the breadth of our experience and the depth of our understanding of competition authorities around the world. We regularly appear before the UK’s Competition and Markets Authority and the European Commission and other authorities in the markets where we operate.

We strive to provide pragmatic, commercial solutions, not purely legalistic opinions. These are based on our many years of experience of the practical application of competition laws, gained from working on numerous leading cases across many sectors, including energy, financial services, media, retail, transport and utilities.

We advise on the full range of competition issues, including merger control, cartel and market investigations (including dawn raids), commercial agreements, compliance policies and training, sectoral regulation, state aid/subsidy control and competition litigation.
