The inquest into the death of a nurse at King Edward VII's Hospital Sister Agnes found hanged after she took a hoax call concerning the Duchess of Cambridge is due to begin.
Jacintha Saldanha was found dead on 7 December 2012, three days after taking the call from two Australian radio DJs.
The DJs phoned the hospital and Mrs Saldanha had put the call through to the ward where the pregnant duchess was staying. Another nurse there revealed confidential medical details.
The inquest at Westminster Coroner's Court is due to last up two days.
According to the BBC, the DJs who made the prank call, Michael Christian and Mel Greig, are not among the list of witnesses, but their employer will make a statement.
