Call to account: Michael Christian and Mel Greig. Scotland Yard has officially asked Australian police to consider laying charges over the hoax phone call by 2Day FM radio DJs to a London hospital that was treating the Duchess of Cambridge for a pregnancy-related illness. The hoax call was made to the King Edward VII Hospital on 4 December 2012. A spokeswoman for the Metropolitan Police in London told Fairfax that on Tuesday this week they sent their file on the incident to the Australian Federal Police and New South Wales police. Tragedy: Jacintha Saldanha. "The MPS has requested that consideration is given as to whether any offences were committed under Australian legislation," the spokeswoman said. She could not confirm the contents of the file, nor whether any specific suggestions were made over who should be charged or with what offences. In December last year Mel Greig and Michael Christian broadcast a prank call in which they tricked hospital staff into putting them through to where the Duchess was being treated, and received confidential information about her health. The nurse who put the call through, Jacintha Saldanha, committed suicide three days later and left a note blaming the hoax. An inquest into her death is due in two months' time. UK police investigated and passed a file to the Crown Prosecution Service in December. However, in February the CPS advised that no charges would be brought in the UK. Ex-presenter could receive huge payout Royal hoax DJ Mel Greig could get a "six- or seven-figure payout" by accusing 2Day FM's parent company, Southern Cross Austereo, of "failing to provide a safe workplace." That is the view of Nowicki Carbone managing partner Anthony Carbone, who said the station appeared to have been "playing with fire" by encouraging questionable stunts - and that Greig has a "very strong case" against her employer.
