The Chief Executive of the NHS, Sir David Nicholson, has admitted giving incorrect evidence to MPs.
Mr Nicholson yesterday told MPs the former head of United Lincolnshire NHS Trust, Gary Walker, had not explicitly identified himself as a whistleblower or raised concerns about patient safety.
However, in a letter to Margaret Hodge MP, who chairs the Public Accounts Committee, Sir David said after "reviewing correspondence", Mr Walker had identified himself as a whistleblower in a letter in July 2009.
Sir David added the action taking in response to Mr Walker's letter was "appropriate"
Mr Walker was sacked from his job in 2010, allegedly for swearing in a meeting. However, he says the real reason was his refusal to prioritise waiting list targets over emergency care for patients, and says he was subject to a "gagging clause" as part of the terms of his pay-off.
