| PERTH, Australia
PERTH, Australia The Australian radio station behind a prank phone call to a London hospital that was treating Prince William's pregnant wife Kate said on Saturday it had done nothing wrong and no one could have foreseen the tragic outcome.
There has been renewed soul-searching over media ethics after Jacintha Saldanha, 46, the nurse who was duped by the station's call to the King Edward VII hospital, was found dead on Friday in a suspected suicide.
The hoax, in which the radio hosts - posing as the Queen and Prince Charles despite Australian accents - successfully inquired after Kate's medical condition, has made worldwide headlines.
On Saturday, Australians from Prime Minister Julia Gillard to people in the street expressed their sorrow and cringed at how the hoax had crossed the line of acceptability.
Two large companies suspended their advertising from the popular Sydney-based station and a media watchdog said it would speak with 2DayFM's owners. Users of social media sites such as Twitter expressed outrage.
The hoax also raised concerns about the ethical standards of Australian media, as Britain's own media scramble to agree a new system of self regulation and avoid state intervention following a damning inquiry into reporting practices.
Southern Cross Austereo Chief Executive Rhys Holleran told a news conference in Melbourne on Saturday that the company would work with authorities in any investigation, but that it was too early to draw conclusions.
He said he was "very confident" that the radio station had done nothing illegal.
"This is a tragic event that could not have been reasonably foreseen and we are deeply saddened by it. Our primary concern at this stage is for the family of Nurse Saldanha."
Holleran added that 2DayFM radio hosts Mel Greig and Michael Christian were "completely shattered" by Saldanha's death. The pair will stay off the air indefinitely, he said.
Two high profile Australian firms, the Coles supermarket group and phone company Telstra, said on Saturday that they were suspending advertising with the station. Others were expected to follow suit.
Austereo said all advertising on 2DayFM had been shelved until at least Monday in a mark of respect to advertisers whose Facebook pages were inundated with thousands of hate messages.
The Twitter accounts of Greig and Christian were removed shortly after news of the tragedy in London broke.
SOCIAL MEDIA OUTRAGE
Social media were inundated with angry messages to the radio station and its hosts in what has become the latest shock radio story to rile the Australian public.
In 2010, 2DayFM was reprimanded by Australia's independent communications regulator after a radio host in 2009 talked a 14-year-old girl into revealing on air that she had been raped, prompting community outrage and an advertiser backlash.
So-called "shock jock" radio announcers are frequently denounced in Australia for their deeply personal and often derogatory attacks on politicians and ordinary citizens.
Communications Minister Stephen Conroy said that the independent broadcast regulator, the Australian Communications and Media Authority (ACMA), had received complaints about the royal hoax.
The British royal family has long had an uneasy relationship with the media, which sank to its lowest after the 1997 death of Prince William's mother Diana in a Paris car crash.
Palace officials acted swiftly this summer when a French magazine printed topless photos of Kate on holiday, taking legal action to curb republication for fear of a repeat of the relentless media pursuit of Diana.
Saldanha's death threatens to cast a pall over the enthusiastic public welcome given to Kate's pregnancy, which dominated newspaper front pages this week from her admission to hospital on Monday to her departure on Thursday.
The royal family emerged from years of criticism that it was a dated and out of touch institution and is enjoying a surge in popularity in Britain following Kate and William's wedding last year. The impending royal baby will only boost public affection.
Elaborate celebrations marking the 60th anniversary of the queen coming to the throne and her appearance at the opening of the London Olympics this summer - where a stunt double parachuted into the stadium - have all contributed to a more positive royal relationship with Britons.
