Four businessmen will be appointed today to drive the next stage of the government's efficiency review aimed at releasing billions for investment in public services after 2010.

Patrick Carter, the Labour peer who chaired the government's review of Wembley Stadium, will take forward a study of the public sector's use of property after the National Audit Office found £330m - more than a third of the amount departments spend on offices - could be saved if private sector best practice was followed.
