Former shadow charities minister Greg Clark, who now holds the Tory brief for energy and climate change, accused the government loan fund of "doctoring a historical press release" (24 September, page 1).
Clark's comments came after Futurebuilders deleted references to its £2m award to Catz Club from a press release published in 2005 when it discovered that the charity had been accused of making an unlawful donation to the Labour Party. It also removed the charity from a list of investees.
"It was wrong and we definitely should not have done it," said Lewis. "We will not do it again." He said he was on holiday when a temporary member of staff changed the details.
Clark said Lewis's admission was "refreshingly candid" but added: "It does touch on the transparency of Futurebuilders, which is a public body and needs to be accountable for its decisions."
Cabinet Office minister Liam Byrne has agreed to a request by his Conservative shadow, Francis Maude, to investigate the roles played by Baroness McDonagh, Labour's former general secretary, and ex-Labour fundraiser Amanda Delew in the funding of Catz Club (Third Sector Online, 9 October).
McDonagh is a former trustee of the charity, and Delew fundraises for it.
