The Sun has been banned from William’s official photocalls for an apparent breach of an agreement to leave him in peace after a pre-arranged photoshoot in the Swiss ski resort of Klosters on Sunday.
Clarence House announced the action as it worked to salvage the voluntary media pact which protects the young royal while he remains in university education.
According to the newspaper, Kate Middleton is William’s first serious girlfriend, but the Prince of Wales’s press office refused to comment on the matter.
The Sun stood by its story last night, branding the photographs “delightful.”
“Our story about Prince William and his girlfriend Kate Middleton is 100% true,” a spokeswoman said. “Therefore, there is a strong public interest in publishing these delightful photographs.
“However, The Sun is irritated that its royal photographer, Arthur Edwards MBE, has been banned from royal events.
“We all know he takes the royal family’s favourite photographs and we shall be launching an ‘Our Arthur Is Innocent’ campaign tomorrow.”
Royal aides were furious after the newspaper used pictures, under the headline “Wills gets a girl,” of the 21-year-old and his flatmate on the Alpine slopes.
William, who is continuing his week-long holiday with his friends, is understood to be upset at the images.
Heir to the throne Charles was also said to be irritated, with both princes feeling that they went out of their way to provide a good photoshoot at the weekend.
The Sun will also be frozen out of pre-arranged events involving 19-year-old Prince Harry.
Clarence House said the ban would last for the time being and that the Press Complaints Commission was not being involved in the matter.
