There have been 3600 complaints to the press watchdog about naked photos of Prince Harry published in The Sun.

The tabloid became the first British newspaper to carry the pictures on Friday, arguing the move was in the public interest and a crucial test of the country's free press.

The Press Complaints Commission (PCC) said they came from members of the public and none from St James's Palace or any other representatives of the royal.

The pictures of him frolicking in the nude with an unnamed woman while on holiday in Las Vegas made headlines around the world but St James's Palace asked UK papers, via the PCC, to respect Harry's privacy.

Sun managing editor David Dinsmore said the paper had "thought long and hard" about whether to use the pictures and said it was an issue of freedom of the press rather than because it was moralising.

London Mayor Boris Johnson said he had a "deafening indifference" to the publication of the naked photos. He said: "The real scandal would be if you went all the way to Las Vegas and you didn't misbehave in some trivial way."
