The Prime Minister, David Cameron, will look to calm nerves within in his fractured Coalition government when he addresses the House of Commons today.
David Cameron returned to the U.K. late on Friday afternoon from the summit in Brussels where he received congratulations from his eurosceptic backbenchers having vetoed the new treaty earlier in the day.
But the deputy prime minister and Lib-Dem party leader, Nick Clegg, who was telephoned at 4am to be told of the veto, has attacked Cameron over his decision to reject the new treaty calling the decision to pull away from the European Union as "bad for Britain."
The interview, which may have surprised Cameron after his deputy had initially appeared to support his decision, has forced the Conservative leader to make a statement to MPs in the Commons at 3.30pm later today.
Junior members of the Liberal Democrats are said to be "deeply concerned" by the unfolding events at the summit on Friday which has put the U.K. on the "outside of a two-tier Europe", according to Clegg. The Lib Dem chief secretary to the treasury, Danny Alexander, told the BBC Today Programme the government should now focus on not being the "odd man out" in Europe.
The deputy PM will meet with business leaders to discuss a pro-EU agenda in what he calls a "political push back" against the Tory eurosceptics.
Labour leader Ed Miliband has called on Mr Cameron to use his statement to MPs to "explain why he did something that was so bad for Britain and bad for British jobs".
"He did this because the Eurosceptic wing of the Conservative Party has effectively taken over and that isn't good for the national interest," the Labour leader said.
