US giant Wilmer Cutler Pickering Hale and Dorr is losing its first London partner since its landmark merger, with litigation expert David Capps leaving for a senior role at UBS.

Capps, who only joined the City base of legacy Wilmer Cutler & Pickering in 2002 from DLA, is leaving on 12 October to become head of litigation for Europe, the Middle East and Africa at the investment bank.
