Speaking of the death of nurse Jacintha Saldanha, David Cameron has said it was a "terrible, terrible case" and lessons should be learnt.
Speaking at the House of Commons Liaison Committee, he said: "This was a dreadful case, it was an absolute tragedy for the family.
"When you read of how hard she had worked across her life and all the things that she had done, and how much she cared about health and looking after people, it's a terrible, terrible case and as I said yesterday, I'm sure there are lessons to learn.
"I think when these things happen, having the full facts of the case, it doesn't bring anyone back but I think it does help people come to terms with what has happened."
An inquest has heard that the nurse who transferred a prank call about the Duchess of Cambridge was found hanging in her nurses' quarters.
Jacintha Saldanha's colleagues discovered her hanged in her room in the King Edward VII's Hospital nursing quarters, her inquest has heard.
The family of Jacintha Saldanha say they miss her 'every moment', as Australian hoax DJs say they are 'heartbroken' at her death.
