LeBoeuf Lamb Greene & MacRae has swooped on Debevoise & Plimpton’s top-rated UK litigation partner Arthur Marriott QC as the New York firm pledges to maintain investment in its London arm throughout the year.

Marriott joined LeBoeuf’s 60-lawyer London office on 1 July. He has been a partner at Debevoise’s London office since 1997, after he left the equity of legacy Wilmer Cutler & Pickering. He joins the firm alongside Debevoise associate Deborah Ruff, who becomes a partner at LeBoeuf.
