Here is the recording of two Australian radio presenters making a prank call to the private King Edward VII hospital where the Duchess of Cambridge is being treated.
The hosts, who present a show on 2dayFM called The Summer 30, were put through to the Duchess' ward, but the nurse's responses have been omitted in the interests of confidentiality.
The Duchess of Cambridge left hospital today, after three days of treatment for a severe form of morning sickness.
A nurse disclosed information about Kate's condition to two DJs who rang the hospital claiming to be the Queen and Prince Charles.
The Duchess of Cambridge is to spend another night in hospital being treated for acute morning sickness but is said to be feeling better.
