Slaughter and May fields a financial regulation team adept in supporting a range of clients — including insurance firms, investment groups, banks, payment service providers, and asset managers — in the full array of non-contentious mandates. Co-head Jan Putnis advises a broad range of financial institutions on complex regulatory matters, corporate transactions, structural reforms, and post-Brexit business strategies, with particular expertise in governance, regulatory compliance, recovery and resolution regimes, and multijurisdictional corporate restructurings. Fellow co-head Nick Bonsall is skilled in complex prudential regulatory matters, capital efficiency transactions, financial institution reorganisations, and portfolio acquisitions and disposals, with a specialism in UK and EU solvency and governance regimes, supervisory and contentious regulatory issues, and Brexit-related restructuring. Adept in supporting fintech firms and challenger banks on transactional and advisory matters, David Shone frequently counsels on capital instrument structuring and group reorganisations, particularly for regulatory and strategic purposes. Kristina Locmele is a further key contact.

I positively enjoy working with this Slaughter and May team, which is not something I can say for every external firm I use.'
