The Sun will today attempt to mount a High Court challenge to lift the injunction banning the identification of a footballer who had an affair with Big Brother star Imogen Thomas.
The paper says it has instructed lawyers to ask the High Court to lift the gag on naming the Premier League player after a picture purporting to be him was splashed over the front page of the Sunday Herald in Scotland.
It adds: "The Sun is seeking a hearing at the Royal Courts of Justice where we will ask a judge to allow us to name the player known in legal documents only as CTB. Our move comes after Prime Minister David Cameron today described the privacy rulings affecting newspapers as 'unsustainable' and 'unfair'."
The Sun also claims: "Yesterday's disclosures will make it virtually impossible for the footballer's highly-paid lawyers to argue his name is not already in the public domain."
