So David Cameron believes that in Brussels he has secured a deal to limit the increase in the EU budget to 2.9%
Has he never read the Lisbon Treaty? He spent enough time denouncing it last year, but it seems that he never did get around to reading it, and nor did most of the British journalists commenting on this week's European Council meeting.
The European Parliament has budgetary powers that match those of the Council. Governments can't do a deal without the consent of the Parliament, and the Parliament negotiating position is to call for a 5.9% increase.
Personally I agree with Cameron; no way should the EU budget next year increase by more than the rate of inflation. That's how I voted, as did the British Liberal Democrat delegation of MEPs. But we were on the losing side.
Real negotiations between Council and Parliament have yet to begin. The MEPs will not get their 5.9% increase. But I bet that the governments aren't able to limit the increase to 2.9%.
