A nurse at a London hospital who took a hoax call about the Duchess of Cambridge has been found dead.
The Duke and Duchess of Cambridge said in a statement they were "deeply saddened" by the death of the nurse, named as Jacintha Saldanha.
King Edward VII hospital paid tribute to "a first class nurse who cared diligently for hundreds of patients".
Details of the pregnant duchess's medical condition were unwittingly revealed to two Australian DJs.
Mel Greig and Michael Christian, from Sydney radio station 2Day FM posed as the Queen and Prince Charles in a call early on Tuesday morning.
Rhys Holleran, chief executive of SCA, the company which owns the station, said in a statement the pair will not return to their show until further notice out of respect for Mrs Saldanha.
The duchess had been admitted on Monday for acute morning sickness, and was discharged on Thursday.
BBC royal correspondent Peter Hunt said he understood Mrs Saldanha - who was staying in hospital accommodation close to King Edward VII hospital - 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 who was married with two children, answered the telephone because it was 05:30 GMT and there was no receptionist on duty.
The BBC understands Mrs Saldanha had not been suspended or disciplined by the hospital.
The BBC's Nicholas Witchell said it had been suggested to him that she had felt "very lonely and confused" as a result of what had happened.
The St James's Palace statement said the duke and duchess "were looked after so wonderfully well at all times by everybody at King Edward VII Hospital, and their thoughts and prayers are with Jacintha Saldanha's family, friends and colleagues at this very sad time".
A palace spokesman later added that "at no point did the palace complain to the hospital about the incident".
On the contrary, we offered our full and heartfelt support to the nurses involved and hospital staff at all times." - BBC
