David has extensive experience in contentious regulatory work, with a particular focus on FCA and other financial services investigations.  He has acted for investment banks, asset managers, insurance and private wealth management firms, and for individuals employed by them, in some of the most high profile investigations to date.  He advises on a wide range of contentious regulatory matters, but has a particular focus on market abuse, the handling of inside information, and financial crime systems and controls (particularly anti-money laundering).  His work includes advising on culture, governance, and non-financial misconduct.

Since moving to Addleshaw Goddard as a partner in October 2018, with a brief to grow the firm's contentious regulatory practice, David has acted in some highly sensitive and innovative new instructions and developed a strong reputation in the market ("he has been instrumental in taking the Addleshaw Goddard team from strength to strength since his arrival and has been involved in some ground-breaking work", Legal 500 2022).

David is highly experienced in cross-border work, having spent time living and working in (among other places) France, Italy, and Hong Kong.
