Following the departure of former practice chair Charlie Lightfoot in October 2023, James Rogers, who is experienced in corporate, commercial, technology, M&A, licensing, and joint venture disputes, leads the practice. Jason Yardley represents hedge funds, privately-owned groups, family offices, sovereign states, and energy and telecoms companies, and Christian Tuddenham is ‘a star practitioner’.
