Details of the payment to Sir Greg Martin, the former head of the Durand Academy in Stockwell, south London, emerged on Monday during a hearing of the Commons public accounts committee, which is investigating academy accounts and performance.
It is the latest development in a long-running saga involving Martin, who was knighted for services to education and was once a favourite of Tory ministers, before falling out of favour as concerns grew about financial management and governance at the school.
