Dr Liam Fox has just given a speech at the Tax payers alliance.
“There will be those that say that this is the wrong time and that it is politically difficult or even impossible. These are the perpetual arguments for inertia. This is not the time for party political games or tactical point scoring. Our National Interest is at stake and that trumps all other considerations. We must rise to the challenge.”
David Cameron and Liam Fox appear to be contemplating the same sort of referendum - a post renegotiation poll. What separates them is that the prime minister is clear that Britain needs to stay in whereas his former defence secretary is now ready to contemplate getting out. That's the divide that really matters.
