Signature Litigation has appointed Mark Beardsworth and Duncan Grieve as partners in its London office, marking the launch of its global white collar crime and investigations practice. The duo joins from Goodwin Proctor and Cadwalader, Wickersham & Taft respectively, bringing decades of experience in high-profile investigations and cross-border matters.
Mark Beardsworth (pictured) has acted in some of the UK’s most significant Serious Fraud Office investigations, including those involving IKEA, BAE Systems, Rolls Royce, and Barclays Qatar. He also advises on corporate governance and compliance, particularly during M&A and distressed scenarios. ‘I am delighted to be joining Signature in London and to work alongside Duncan to add weight to the firm’s global expertise,’ said Mark.
Duncan Grieve brings extensive experience in cross-border investigations, particularly in Brazil, Portugal and Lusophone Africa. A fluent Portuguese speaker, he advised on Operation Car Wash and negotiated leniency agreements with Brazilian authorities. ‘I am excited to be working with Mark again and to contributing to Signature’s disputes-only platform,’ Duncan commented.
Graham Huntley, founding partner at Signature Litigation, welcomed the appointments, calling Mark and Duncan ‘formidable operators’. He added: ‘Our platform as a disputes-only law firm provides fresh opportunities for Mark and Duncan to extend their reach collectively in London and internationally.’
