Sir David Nicholson has written a letter outlining his intention to retire in March next year to the chair of NHS England Professor Malcolm Grant. In it he writes:
Whilst I believe we have made significant progress together under my leadership, recent events continue to show that on occasion the NHS can still sometimes fail patients, their families and carers. This continues to be a matter of profound regret to me but please know that on a daily basis I continue, and will always continue, to be inspired and moved by the passion that those who work in the NHS continue to show.
