Speaking on ITV's Daybreak programme the Health Secretary Jeremy Hunt put forward his case for why Britain needs to change its relationship with Europe.
"We have to change our relationship with Europe because if we're going to be successful in the global race we have to realise Europe is in the slow lane economically compared to what is happening in Asia or America where the Prime Minister is now."
"So I think what the Prime Minister is doing is saying we've got to change that relationship so that we can be more successful and then we've got to give the British people a choice."
Cameron has pledged to back a Conservative MP's EU referendum bill, as Cable labelled the move potentially 'damaging' for the country.
114 Conservative backbenchers have voted in favour of a eurosceptic motion to amend the Queen's Speech in defiance of the Prime Minister.
David Cameron has denied he has buckled under pressure from his backbench MPs over the EU debate.
