Allen & Overy (A&O) is taking on the global IT services director from BP for a newly created post of director of IT and chief information officer.
Dave Burwell's appointment is the result of the firm's reorganisation of its four non-legal heads of department. The firm currently has directorships for finance, human resources, marketing and business services, which covers IT, property and purchasing.
Property and purchasing will now become the responsibility of the director of finance and a new director of IT replaces the director of business services.
Business services director Rodney Barker is retiring from the firm. Burwell will take charge of the firm's information management strategy, its client facing and back office systems, and its e-commerce activities, including client extranet site newchange.
A&O managing partner John Rink says: "Reflecting the fact that information technology is crucial to our business, we are making an appointment at a very senior level to lead the function."
