With particular strength in far-reaching, multijurisdictional matters, as well as novel and complex areas of competition law, Slaughter and May’s leading antitrust practice is well placed to manage merger control, cartel and market investigations, and subsidy-control matters. The team caters to an enviable roster of clients from the food and beverage, technology, construction, and insurance sectors, among others. Co-chair Claire Jeffs is known for her broad contentious and non-contentious competition expertise, and co-chair Bertrand Louveaux’s practice encompasses merger control, litigation, inquiries, and complex investigations. Isabel Taylor is adept at State aid and subsidy-control matters. Recent highlights for William Turtle include advising Vodafone on the proposed joint venture with Three UK. Tina Zhuo coordinates global merger-approval strategies, and Jessica Staples, experienced in both behavioural investigations and market studies, is also recommended.
