THE nurse found dead after being duped by a prank call from two Australian radio DJs to the hospital treating the Duchess of Cambridge was reassured a number of times by senior management, it said last night.

John Lofthouse, the chief executive of King Edward VII Hospital in London, where the pregnant royal was treated last week, made his comments after it was reported Jacintha Saldanha, 46, had left a suicide note criticising staff.

Mr Lofthouse said the nurse was the victim of a "cruel trick" by presenters from 2DayFM. But he said senior staff did not blame her and offered her time off and counselling.

In reply to MP Keith Vaz, Mr Lofthouse said: "Jacintha believed the call was genuine, and she felt it appropriate to put the call through. We stand by her judgment. Following the hoax call, Jacintha was reassured on a number of occasions by senior management that no blame was attached to her actions and that there were no disciplinary issues involved."

Mrs Saldanha, from Bristol, was found hanging in her nurses' quarters last Friday. The nurse transferred the DJs who posed as the Queen and Prince of Wales, to a colleague who described the condition of the Duchess of Cambridge during her hospital stay for severe pregnancy sickness.

Staff gathered at the hospital for a private memorial service and a mass is due to be held at Westminster Cathedral today.
