Former defence secretary, Dr Liam Fox, has said in a speech calling for a referendum on Britain's membership with the EU:
I do not believe that Britain's national interest is served by its current relationship with the EU. This becomes even more so with the shifting dynamic unfolding before us.
It is not we in Britain who have brought about the fundamental change in the nature of the EU. We stayed outside a single currency project whose flaws have turned out to be exactly as we envisaged and predicted.
But such is the new reality in which we find ourselves that to either ignore or deny this will continue the policy of half-truths and deception which has gone on for far too long.
Former defence secretary Liam Fox has said that the UK should leave the European Union unless there is a rebalancing of their relationship.
Foreign Secretary Hague said there would be a "very, very powerful" case for a referendum if Europe moved towards a more federal system.
