Bit of a predicament for Mr Cameron. Does he comply with the stated will of the House of Commons and insist on a real terms cut in the EU budget, even though that would be comprehensively unacceptable to most of the other member states? Does he veto any alternative outcome, even though his original starting point (of a budget increase equivalent to inflation was one such alternative outcome? And what would a veto achieve anyway, other than kicking the can down the road to another summit later on? And if he were to accept an outcome other than a real terms budget cut, what would the Tory Party do?
I might even feel some sympathy for the poor sod, were it not for the fact that his current predicament is at least in part due to his previous (and continuing) equivocations about an EU referendum, his previous pointless veto on the fiscal compact, his utter failure to build alliances with other member states and - above all - his inability to make up his mind about his policy with regard to the future of the EU.
And that does not excuse the shameless opportunism of the Labour Party.
