Ewan BrownSlaughter and May

Slaughter and May‘s contentious financial services regulatory team is situated in the firm’s global investigations group, led by Richard Swallow, and has a strong reputation for domestic and cross-border regulatory investigations and enforcement actions. Lawyers have substantial experience in benchmark-linked regulatory investigations for the firm’s impressive global financial institutional clients, in addition to market abuse, anti-money laundering and disclosure cases. Deborah Finkler is key to the firm’s offering, regularly handling high court litigation, foreign disputes and regulatory investigations. Ewan Brown is another expert in FCA investigations, often acting in the role of strategic counsel. Holly Ware‘s practice includes cross-jurisdictional investigations, involving regulatory and prosecuting authorities. Jonathan Clark is an expert in benchmark manipulation cases.

Slaughter and May‘s ‘excellent tax team‘ demonstrates ‘a real commitment to the client’s case‘. Key cases that the team have advised on involve a broad range of tax areas, including bank payroll tax, management incentivisation arrangements and transfer pricing, as well as diverted profits tax (‘DPT’). Dominic Robertson, who has a strong background in DPT and transfer pricing, co-heads the tax disputes practice with Richard Jeens. Corporate tax specialist Mike Lane and Steve Edge are key individuals. Ewan Brown and William Watson are also noted. Sarah Lee and Sara Luder retired in 2020.

Praised for its ‘360-degree service’, Slaughter and May’s recent track record includes acting on some of the longest-running, high-profile fraud and corruption investigations conducted by the SFO. In addition, the team is adept at handling internal investigations for multinational companies, prominent financial institutions, and government and public sector bodies. For more demanding assignments, clients also benefit from the firm’s dedicated legal tech team, which is particularly helpful for document reviews and e-disclosure; a legal project manager is also often involved in coordinating investigations. The group stands out for its cross-border work; with disputes and investigations practice head Richard Swallow singled out for being ‘extremely smart, tough-minded and strategic’ – skills he successfully utilises in multi-jurisdictional investigations conducted by the SFO, the DOJ and other authorities overseas. The practice has seen a number of significant changes over the last year.  Former practice head Sarah Lee retired from the partnership at the end of 2020, with the firm hiring senior counsel Angela Taylor from Travers Smith LLP at the same time. The global investigations group is now jointly led by Jonathan Cotton (‘hugely experienced and wise’) and Ewan Brown (‘frighteningly bright’). Tim Blanchard was promoted to partner in May 2020, while Ella Williams has been a senior counsel since November 2020. Gayathri Kamalanathan joined the firm from a bank in April 2021, but is already garnering praise for her deep understanding of the financial services sector.
