Oliver Middleton, Chair of the London Litigation & Trial Department, acts for clients in all manner of commercial disputes, with a particular focus on complex, high-profile commercial litigation including financial, corporate, and shareholder claims. He draws on successful experience with some of the most significant class actions in the UK.

Oliver has experience across a wide range of commercial litigation matters and regulatory investigations, including:

  • Financial litigation
  • Complex contractual claims
  • Shareholder actions (including s.90/s.90A FSMA and unfair prejudice claims)
  • Bondholder disputes
  • Trust litigation
  • Economic tort claims
  • Insurance disputes
  • Data privacy
  • Breaches of confidence
  • Defamation claims
  • Intellectual property litigation

He represents clients in the banking and financial services, insurance, private equity, media, and technology industries.

Oliver is uniquely positioned to understand significant claims from both claimant and defendant perspectives, as he was previously at a well-known claimant litigation firm. He leverages a sophisticated understanding of claimants’ goals, tactics, and issues — such as book building, working with litigation funders, shareholder class action trends, and settlement strategies. In particular, he draws on insights from his work acting in the RBS Rights Issue Litigation, one of the largest cases before the English Courts and the seminal s.90 FSMA case.
