Allen & Overy (A&O) rainmaker Roberto Casati will go straight to the top of Cleary Gottlieb Steen & Hamilton’s lockstep as part of the deal he secured with the leading New York firm to join its ranks.

As first revealed on legal week.com, A&O Italian senior partner Casati resigned for Cleary on 26 April and joined the New York firm’s Milan branch on 1 May as its first partner based full-time in the city. The deal means Casati, one of Italy’s best known M&A lawyers, is expected to draw more than $2m (£1.12m) annually.
