Celebrity threesome injunction: Supreme Court last option for star known as PJS

The male celebrity known as "PJS" has taken his fight to remain anonymous all the way to the Supreme Court as The Sun On Sunday prepares to reveal details of a threesome he was involved in. The married man, whose spouse is also in the public eye, had until 10pm on Tuesday (19 April) to submit an appeal to the country's highest court or else have the veil over his identity lifted.

His submission came after Lord Justice Jackson, Lady Justice King and Lord Justice Simon said the injunction should be lifted in England and Wales. The celebrity was not named outright because he was given time to appeal their decision. The hearing will take place on Thursday at 9.30am in Courtroom 1.

Lawyers for the The Sun On Sunday's publisher News Group Newspapers argued the restriction had been made a mockery of after the man at the centre of the legal battle was named in America and Scotland.

The Supreme Court must decide if the man's privacy has eroded to the point where the injunction is pointless. The case has echoes of the injunction taken out by former Manchester United footballer and current assistant manager Ryan Giggs in 2011.

The Welshman wanted to conceal an affair with former Big Brother contestant Imogen Thomas but Lib Dem MP John Hemming used parliamentary privilege to reveal his identity. To avoid a repeat of that scenario, Speaker of the House John Bercow banned MPs from discussing the identity of the couple in the House of Commons.
