Asked for David Cameron's response to Sir David Nicholson's retirement and assessment of his record, the Prime Minister's official spokesman said: "He agrees with the Secretary of State for Health."
Mr Cameron's view of Sir David was "unchanged" since the PM responded to the Francis report on Mid-Staffordshire, said the spokesman.
He said he was not aware of ministers discussing the NHS chief's departure with Sir David in advance, adding: "It is his decision to retire."
