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 secured this week with the leading New York firm to dramatically bolster its Italian practice.

As first revealed on, A&O Italian senior partner Casati resigned for Cleary on Monday (26 April) and will join the New York firm’s Milan branch on 1 May as its first partner based full-time in the city.
