Allen & Overy

(A&O) has been rocked by the loss of four partners, including two capital markets rainmakers, in just one week.

Securitisation star Julian Tucker and collateralised debt obligation specialist Angus Duncan are leaving to join the City arms of Shearman & Sterling and Cadwalader Wick-ersham & Taft respectively, as first revealed on www.the lawyer.com (16 March).

Tucker, who is joining Shearman as the head of its structured finance practice, has a strong real estate financing background, having handled all the Canary Wharf deals. His clients include ABN Amro, Barclays Capital and Morgan Stanley.

His hire coincides with the consolidation of Shearman’s securitisation practice into a broader structured finance offering and follows the resignation of its former head of securitisation Mark Raines.

Duncan’s appointment is part of Cadwalader’s push into finance in London. Earlier this month, the firm promoted capital markets lawyer Charles Roberts to partner.

A&O has also lost Brussels competition partner David Harrison, who has joined Berwin Leighton Paisner‘s London office.

Utilities specialist Stuart Harray, who has been a partner at A&O since 1998, is also leaving in the summer to return to New Zealand to join local firm Russell McVeagh (both first revealed on www.the lawyer.com, 16 March).

A&O declined to comment.
