How the Tories could capitalise on the eurozone’s woes

With events in Greece moving at pace, next week’s European Council meeting (which was scheduled to be a low-key affair) could be the place where attempts to resolve the crisis in the eurozone take place. I’m told that Number 10 has now woken up to this possibility and is doing some preparatory work on the matter.
 
But, frustratingly, there’s still no strategy for how David Cameron could use this crisis to advance the British national interest. As I wrote last week, if the eurozone countries decide that a solution will require a treaty change, then Britain has a veto over that — and could use the negotiations to secure various things that Britain wants from the EU. For example, Britain could secure a promise that its budget contribution will not increase in the next seven year budget-cycle or demand a national veto over anything affecting financial services as it is a vital national industry.
