David Cameron has announced a full inquiry into phone hacking and the media on Wednesday, following prime minister's questions.
Cameron concluded a meeting at Number 10 on Tuesday evening with Deputy Prime Minister Nick Clegg and Labour leader Ed Miliband where it was agreed that a judge-led inquiry into phone hacking will have a remit to cover more than just the allegations made against the News of the World.
The inquiry will look at the relationship between the media and politicians, as well as the role of the police.
In addition to meeting with Clegg and Miliband on Tuesday evening Cameron met with Sir Paul Stephenson, the Met commissioner, reportedly to finalise details of the announcement.
MPs from all of the major parties are expected to support Labour's motion in the debate and call on Rupert Murdoch to withdraw his bid to take over all of BSkyB.
Labour MP and opposition spokesman on culture Ivan Lewis said he welcomed the move by the government to support the motion. He told the BBC on Tuesday: "It is a very very clear message - and that message is this - the public of this country will not understand it if the BSkyB deal were to go ahead without all of the criminal matters that are currently under investigation being resolved."
