BRITISH newspapers were warned against publishing naked images of Prince Harry after he was photographed "letting off steam" on holiday in Las Vegas.

The Press Complaints Commission said publication of the images, which show the prince and a woman both naked, constitutes a breach of privacy codes.

The images, which have already been widely published on the internet, were apparently taken on a camera phone as he was partying in a Las Vegas hotel suite.

He had been enjoying an extended weekend break before embarking on the next phase of his military career.

They are believed to be the first intimate images published of a senior member of the Royal Family.

However, there is no suggestion anything other than horseplay is going on between the royal and the unnamed woman.

In the first photograph, the 27-year-old is shown wearing just a necklace and a wristband with his hands around his genitals as a seemingly topless woman stands close behind him.

The nude prince is shown in another picture shielding himself behind an unknown woman who is also naked, with his bottom facing the camera.

US website TMZ, which published the images, claimed they were taken last Friday.

The website said that the pictures appeared after the prince and his entourage met some women in a hotel bar and invited them up to the royal's suite.

The group played a stripping game and someone in the party is thought to have captured the image of the naked prince on a camera phone.

A source said the pictures had been taken on Harry's personal break from work as an Army officer and helicopter pilot.

The source added: "He's been in LA on a private holiday over the weekend. He's been letting off steam before the next phase of his military career."

The pictures of a naked royal come at the end of his eventful long weekend in Los Angeles and Las Vegas that was well documented in the UK media.

Harry was filmed wearing a hat, sunglasses and colourful swimming shorts, socialising at a hotel pool party at the MGM Grand in Las Vegas.

Singer Jennifer Lopez is also thought to have met the royal.

Prince Harry even challenged Olympic gold medal winning swimmer Ryan Lochtie to a race across a pool, but lost.

He is now believed to be on his way home to the UK.

A number of the prince's charities refused to comment, as did the Ministry of Defence.
