The cabinet was reported to have disclosed the four key requirements the Prime Minister wants ahead of the in-out referendum, but they have already been ridiculed by Eurosceptics both inside and outside the Conservative Party for failing to tackle at the migration issue. The demands include an "explicit statement" Britain can stay out of a European superstate and protections for the pound. Mr Cameron also wants a "red card" system for groups of national parliaments to opt out of - or repeal existing - laws.

There are calls for a "new structure" so the nine non-eurozone countries are not dominated by the others. Critics have attacked the proposals for failing to consider issues such as curbing free movements across the continent or treaty changes. UKIP deputy leader Paul Nuttall told Express.co.uk: "The biggest issue in Britain today,according to all the polls, is immigration.

"If he's not even prepared to put on the table the issue of freedom of movement then this isn't worth the paper it's written on. "Is this any real renegotiation? As far as I can see these lines are drawn in sands and certainly not in stone. "It's even weaker than I expected." Government sources have defended the demands by saying there is not enough time before the in-out vote, planned for the end of 2017, to deliver treaty changes.

One senior figure told the Sunday Telegraph, which revealed Mr Cameron's renegotiation requirements today, some migration issues would not be accepted by EU nations. He said: "Reforming free movement is a red line for some of the smaller countries.” That has not stopped a number of politicians mocking the demands. UKIP MEP for the East Midlands Roger Helmer said: "Has Cameron set his EU demands so low in the hopes that he can produce a real concession later, like a rabbit out of a hat?"

Tory MEP David Bannerman said: "If correct, this does not look like fundamental reform of the EU." Former Conservative cabinet minister Owen Paterson also criticised the proposals. He said today: “What I want to have is a complete new relationship with our European neighbours based on trade and friendly cooperation but above all making our own laws in our own parliament. "That sadly does not appear to be what our negotiators on behalf of the UK are looking for."
