Mark Tucker's AIA appointment

Bob Benmosche, AIG’s chief executive, has moved to stamp his authority on the insurer after winning a boardroom battle, replacing the head of the company’s giant Asian arm only months before its planned listing. The bailed-out US insurer on Monday named Mark Tucker, a former head of the UK’s Prudential, as executive chairman and chief executive officer. Mr Tucker is to take over from Mark Wilson, the chief executive of AIA since 2006. Ben McLannahan examines the appointment.
