A nurse at London's King Edward VII hospital who took a hoax call about the Duchess of Cambridge has been found dead.
The hospital, which has paid tribute to "a first class nurse", named the woman as Jacintha Saldanha.
Police were called at 09:35 GMT to reports of a woman found unconscious at an address in central London.
Details of the pregnant Duchess's medical condition were unwittingly revealed to two Australian DJs.
The pair, from Sydney radio station 2Day FM, posed as the Queen and Prince Charles.
BBC royal correspondent Peter Hunt said he understood Mrs Saldanha was the person who answered the call from the Australian DJs and was not the nurse who discussed the duchess's medical condition.
Mrs Saldanha, a duty nurse, answered the telephone because it was 05:30 GMT in the morning and there was no receptionist on duty.
The BBC understands Mrs Saldanha had not been suspended or disciplined by the hospital.
The hospital said in a statement: "We can confirm that Jacintha was recently the victim of a hoax call to the hospital.
"The hospital had been supporting her throughout this difficult time."
It added: "Jacintha has worked at the King Edward VII's Hospital for more than four years.
"She was an excellent nurse and well-respected and popular with all of her colleagues."
Scotland Yard said the death was being treated as unexplained and enquiries were continuing.
The duchess was admitted on Monday for acute morning sickness, and was discharged on Thursday.
