  • Profile
  • Experience
  • Key contacts

Competition law compliance is a high priority for businesses worldwide. Competition authorities are increasingly cracking down on cartels, abusive and other anti-competitive practices as well as strictly enforcing their merger control rules. In the present day, no company or employee can afford to ignore the civil and criminal sanctions that may be applied under the competition rules.  Nor can companies consider themselves immune from the possibility of third party private damages actions.

Based in London and Paris, our competition team have expertise across the full spectrum of competition law and advise an international client base across a range of industry sectors.

In particular, we have extensive experience of:

  • Cartels – including dawn raids, investigations, whistleblowing, leniency and settlement agreements.
  • Abuse of market power – including the negotiation of commitments.
  • Merger control – including national and multi-jurisdictional filings worldwide.
  • Compliance – including advising on compliance programmes as well as conducting audits/mock dawn raids.
  • Commercial agreements – including assisting with the review and drafting of distribution, selective distribution, franchising, agency and other arrangements to ensure compliance.
  • Complaints – including advising on third party interventions.
  • Market investigations – including advising on consumer and industry wide transparency issues and solutions.
  • Private actions and litigation – pursuing or defending against complaints and actions.
  • Public procurement and state aid.

“Quick, pragmatic, competent advisers with great attention to detail... Very client-focused. Highly committed to getting the best service for the clients.”
The Legal 500 UK 2023
