Nathan Willmott - Bryan Cave Leighton Paisner LLP

Within: Financial services

Benefiting from 'deep practical experience', Bryan Cave Leighton Paisner LLP is best-known for its contentious expertise and is recognised as a 'strong choice for anyone looking beyond the Magic Circle'. Team head Nathan Willmott is an 'excellent lawyer' and has vast experience at handling regulatory investigations and enforcement actions both from a purely domestic as well as cross-border perspective. 'Hugely experienced' consultant Sidney Myers 'knows the FCA inside out' and has expertise across a wide array of work including in relation to market manipulation of financial benchmarks and insider dealing. At a more junior level, the 'very knowledgeable and hardworking' Oran Gelb is developing a strong reputation across both regulatory investigations and financial services litigation, and the 'tenacious and ambitious' Polly James is 'very strong on market abuse cases'. James is also fairly active on the non-contentious front (particularly in relation to Senior Managers and Certification Regime matters) and is emblematic of the firm's coordinated and fluid approach in relation to advisory work, mindful as it is to mitigate against potential litigious problems further down the line but seamlessly able to handle any issues should they arise. The 'user-friendly and accessible' Daniel Csefalvay joined the team in October 2017 from Linklaters LLP and is noted for his 'excellent working knowledge of the complicated regulatory regimes'. Csefalvay is particularly active in the wholesale market acting for investment banks, broker dealers, high frequency trading firms and market infrastructure providers on critical regulatory reform projects including MiFID ii. Matthew Baker is 'also very good' and regularly supports the firm's funds clients on regulatory issues. Clients include AIG, Aviva and CBRE Global Investors.
