A famous British actor who won an injunction to prevent claims that he slept with a prostitute from being published has been named in the US.

The married star allegedly paid for sex with Helen Wood, the former escort who once claimed she had an affair with England footballer Wayne Rooney while his wife Coleen was pregnant with their first child.

The Sun newspaper said the court injunction was obtained five years ago to prevent it revealing the actor’s identity in the UK, but a US magazine has now published his name with details of his alleged infidelity. The actor’s name was also circulated on social media.

It comes after an American publication named another celebrity last month, who is alleged to have taken part in extra-marital activities despite the English media being banned from reporting his identity.

Supreme Court judges are still considering whether to lift the injunction in that case, in which the famous man is referred to only as PJS.

Mark Stephens, media lawyer at legal firm Howard Kennedy, said he expected to see more foreign publications naming stars who were subject to privacy injunctions in Britain.

He said: “Global stars seem to have fallen for the soft sell of claimant lawyers promising the earth but delivering a target to the backs of celebrities.

“We can now expect to see a weekly stream of publications in foreign publications, each and every one breaching English privacy orders. ”

Miss Wood, who won Big Brother in 2014, told the Sun that the actor paid £195 through an escort agency to have sex with her in March 2010. She also claimed she used a sex toy on him.

Last month, the president of the Supreme Court said individuals could still challenge the “more intense” dissemination of information that is already in the public arena.

Lord Neuberger said: “The fact that information about an individual is in the public arena does not necessarily prevent that individual from challenging its dissemination more widely, more intensely or more permanently.

“And in the traditional world of hard copy, most information would be difficult to access a year later. Yesterday’s newspaper would be today’s fish and chip wrapping, and tomorrow’s waste material.

“However, in the brave new world of webpages, yesterday’s news will be accessible not merely next year but next century, and it is relatively easily findable through a search engine.”
