The head of the NHS in England, Sir David Nicholson, has told a committee of MPs that he is "absolutely determined" to lead the health service through forthcoming reforms.
Sir David was giving evidence to the Health Committee on 5 March 2013. The committee was conducting an evidence session on the Mid-Staffordshire NHS Foundation Trust Public Inquiry.
There have been calls for Sir David's resignation since a report into failings at Stafford Hospital was published last month.
Sir David was in charge of the regional health authority for part of the period when patients were being mistreated.
He was pressed by MPs about the extent of his contact with Stafford Hospital and why the problems there had not been spotted sooner. He said the NHS was more complex than being just one organisation.
Last month a public inquiry led by Robert Francis published findings into standards of care at Stafford Hospital from 2005-2008.
The inquiry led to heavy criticism of the Mid Staffordshire Trust.
