Rupert Murdoch has been urged to abandon his takeover bid for BSkyB after it emerged that all three main parties will back a call for him to drop his plans.
The Tories and the Liberal Democrats said they would be supporting a motion tabled by Labour leader Ed Miliband when it comes before MPs on Wednesday.
The text insists it is “in the public interest for Rupert Murdoch and News Corporation to withdraw their bid for BSkyB”.
Mr Miliband said: “I welcome news that the Government says it will support our motion.
“It is now for Rupert Murdoch to recognise the strength of public feeling and the will of all the major parties.”
The development comes as the Prime Minister, his Liberal Democrat deputy Nick Clegg and Mr Miliband prepare to hold talks this evening on the phone-hacking scandal.
Labour has called a debate on the row on one of the regular Opposition Days, when it has the opportunity to determine the subject for discussion on the floor of the House of Commons.
In a separate development Rupert Murdoch, his son James, and News International chief executive Rebekah Brooks have been asked to appear before MPs next week to answer questions about the phone-hacking scandal.
Commons Culture Committee chairman John Whittingdale originally said he was “very pleased” that the trio had accepted an invitation to give evidence but doubt has now emerged about whether they will in fact appear.
