David Cameron's "vague" promise of a renegotiation of Britain's membership of the European Union will damage economic growth and distract the Prime Minister's attention from more important issues such as jobs, immigration and crime, Nick Clegg warned today.
He told LBC 97.3 radio that Mr Cameron had announced the "so-called" renegotiation and an in/out referendum on UK membership "for his own political purposes".
But he indicated that the referendum promise would not necessarily prevent Liberal Democrats entering into a renewed coalition with Conservatives in the case of a hung Parliament after the 2015 general election.
To the surprise of many Lib Dems, Nick Clegg appears to have played down the importance of the Coalition's divide on an in-out referendum.
Business leaders in Davos are worried about the Prime Minister's pledge to put Britain's membership of the European Union to a referendum.
With some in France keen to "roll out the red carpet" for a British exit, Germans favouring decentralisation welcome EU renegotiation talks.
