The British nurse who committed suicide after a prank radio call by two Australian DJs reportedly left a suicide note blaming them for her death.

The handwritten note from Jacintha Saldanha was addressed to her managers at the private King Edward VII's Hospital in London, where Prince William's wife Katherine was being treated for acute morning sickness in December, the Sunday Times reported.

In one of three letters she left behind, the Indian-born nurse wrote: "Please accept my apologies. I am truly sorry. Thank you for all your support".

"I hold the Radio Australians Mel Greig and Michael Christian responsible for this act. Please make them pay my mortgage. I am sorry. Jacintha."

At an initial hearing in December, the inquest into the 46-year-old's death heard that Ms Saldanha was found hanged in staff accommodation near the hospital.

She also had marks on her wrist, and there were no suspicious circumstances over her death.

Ms Saldanha had accepted the hoax call from the DJs pretending to be Queen Elizabeth II and William's father Prince Charles, before passing it onto a colleague, who divulged details of Catherine's morning sickness.

The broadcast of the call made global headlines and Ms Saldanha was found dead three days later, triggering a major backlash against the radio network and the hosts.

The Sunday Times said that in another of the suicide notes, the nurse said she did not blame her colleagues for the distress that drove her to kill herself.

The other reportedly contained instructions for her funeral, which took place in India.

Mel Greig, one of the two DJs who made the prank call, has been granted permission to appear as an individual at the upcoming inquest into Ms Saldanha's death.

According to a statement from her lawyers Slater and Gordon, Ms Greig was prepared to answer any questions the coroner or the family's lawyers put to her.

"Ms Saldanha's suicide was a devastating tragedy and Ms Greig’s thoughts have been with the family ever since," the statement said.

"She is determined to address any questions surrounding her role in these tragic events as part of the inquest."

The inquest is due to resume on Thursday, but media reports say it may be delayed.
