NHS nursing: Up to 40,000 posts unfilled

The Royal College of Nursing (RCN) estimates that the NHS in England has as many as 40,000 unfilled posts. It's now calling for staffing levels to be guaranteed in law.

The Conservatives say there are thousands more nurses on the wards of acute hospitals in England.

But the chief executive of the Royal College of Nursing, Janet Davies, says the situation is unacceptable.
