The Australian radio presenters who duped a nurse into helping reveal details about the pregnant Duchess of Cambridge's health are to break their silence about their prank call.

Mel Greig and Michael Christian will appear on three television shows to speak for the first time about the call in which they tricked two nurses at London's King Edward VII's hospital.

Jacintha Saldanha, 46, who took the initial call before putting the pair through to a colleague, was found dead on Friday in what appears to be a suspected suicide.

Ms Greig and Mr Christian, DJs on the station 2Day FM, will be quizzed about the incident on the Australian TV programmes A Current Affair, Today Tonight and The Project. The interviews with Ms Greig and Mr Christian will be broadcast at 7.30am GMT, and will be shown on Sky News. Interviews with the pair were carried out by two broadcasters, but a third was cancelled after Ms Greig broke down.

In tears, she spoke of the moment she discovered Ms Saldanha had died, saying: "I remember that moment very well because I haven't stopped thinking about it since it happened. I remember my first question was, 'Was she a mother?'."

The pair are on indefinite leave from the station and are receiving "intensive psychological counselling" to deal with the tragedy, The Australian newspaper said.

The boss of Southern Cross Austereo said the radio station had repeatedly tried to contact Ms Saldanha and her nurse colleague to seek their permission before they broadcast the conversation. Chief executive Rhys Holleran told Melbourne radio station 3AW: "It is absolutely true to say that we actually did attempt to contact those people on multiple occasions."

Bosses at Southern Cross Austereo said on Sunday the station is is reviewing its broadcasting practices and will help with any investigations into Ms Saldanha's death. They spoke out after British police confirmed officers had contacted their Australian counterparts over the death.

Ms Saldanha's family believe she died because of overwhelming "shame", it was reported. She was a "proper and righteous person" who would have been "devastated" about what happened, her brother Naveen told the Daily Mail.

The Australian Communications and Media Authority (ACMA), which regulates radio broadcasting, is looking at the Commercial Radio Code of Practice to see whether the presenters breached it. It will be looking at point six of the code, which is "to prevent the unauthorised broadcast of statements by identifiable persons".
