A nurse who was working at the hospital that treated the Duchess of Cambridge when telephone hoaxers called earlier this week has been found dead.
Jacintha Saldanha was found at an address near the King Edward VII Hospital in London this morning.
The hospital said in a statement: "We can confirm the tragic death of a member of our nursing staff, Jacintha Saldanha.
"Jacintha has worked at the King Edward VII Hospital for more than four years. She was an excellent nurse and a well-respected and popular member of staff with all her colleagues.
"We can confirm that Jacintha was recently the victim of a hoax call to the hospital. The hospital has been supporting her at this difficult time."
Hospital chief executive John Lofthouse said: "Our thoughts and deepest sympathies at this time are with her family and friends.
"Everyone is shocked by the loss of a much-loved and valued colleague."
The family of Jacintha Saldanha have said that they " are deeply saddened by the loss of our beloved Jacintha".
Scotland Yard said the death was not being treated as suspicious.
Two Australian radio DJs impersonated Britain's Queen Elizabeth and the Prince of Wales to dupe Ms Saldanha into giving a condition update on Kate, who was suffering severe morning sickness at the private hospital.
The presenters, from 2Day FM, remarked during their show how their efforts were the "easiest prank call ever made", as they put on mock British accents they later described as "terrible".
A statement from Southern Cross Austereo (SCA) and 2Day FM states" that they are deeply saddened by the tragic news of the death of nurse Jacintha Saldanha from King Edward VII's Hospital."
It says: "we extend our deepest sympathies to her family and all that have been affected by this situation around the world."
Chief Executive Officer Rhys Holleran has spoken with the presenters, they are both deeply shocked and at this time we have agreed that they not comment about the circumstances.
SCA and the hosts have decided that they will not return to their radio show until further notice out of respect for what can only be described as a tragedy.
In a statement today, Scotland Yard said officers were called at around 9.35am this morning to a report of a woman found unconscious at an address in Weymouth Street, W1.
It said: "London Ambulance Service attended and the woman was pronounced dead at the scene. Inquiries are continuing to establish the circumstances of the incident.
"The death is not being treated as suspicious at this stage."
Speaking on Tuesday, Mr Lofthouse condemned the hoax call, made in the early hours of that day and said that the hospital was considering legal action.
The 2Day FM presenters, Mel Greig and Michael Christian, later apologised for their actions as did their radio station.
The station was expected to issue a statement about the death later today.
The DJs made their call at around 5.30am on Tuesday and are thought to have been put through to Ms Saldanha, 46.
The nurse told them: "She's sleeping at the moment and she has had an uneventful night and sleep is good for her.
"She's been given some fluids to rehydrate her because she was quite dehydrated when she came in but she's stable at the moment."
The nurse added: "She hasn't had any retching with me since I've been on duty and she has been sleeping on and off. I think it's difficult sleeping in a strange bed as well."
The prank call was deeply embarrassing for the hospital.
Mr Lofthouse said on Tuesday: "I've received advice that what the Australian broadcasters did may well have broken the law. On the other hand they've apologised for it so we're going to have a long and careful think about what, if anything, we do."
The prank call was pre-recorded and vetted by lawyers before being broadcast to listeners in Sydney.
In their initial apology the two presenters said: "We were very surprised that our call was put through. We thought we'd be hung up on as soon as they heard our terrible accents.
"We're very sorry if we've caused any issues and we're glad to hear that Kate is doing well."
