What does Cameron actually want back from Brussels?

If you ask what’s the problem with David Cameron’s European strategy, a cacophony of voices strike up. But it seems to me that most of their complaints are tactical when the fundamental problem is strategic: what does Cameron actually want back from Brussels?

Some of those involved in preparation for the renegotiation tell me that this is the wrong question to ask, that what Cameron is seeking is a systemic change in the way the European Union works. But I’m still unclear on what their strategy for achieving this is.

One insider tells me that inside Number 10 they’re ‘terrified of detail’. One can see why. Nearly all Tory MPs can get behind renegotiation but they have very different views on how extensive it should be. But if Cameron is to have a chance of succeeding in this renegotiation he has to know precisely what he wants and what is too high a price to pay for EU membership.
