If the euro zone doesn't come up with a comprehensive vision of its own future, you'll have a whole range of nationalist, xenophobic and extreme movements increasing across the European Union. And, frankly, questions about the British debate on EU membership will just be a small sideshow compared to the rise of political populism.

I totally rule out any arrangements with the SNP — in the same way I rule out any arrangements with Ukip - because there is no meeting point for me with one party that basically wants to pull our country to bits and another party that wants us to pull out of the EU. I would never recommend to the Liberal Democrats that we help establish a government which is basically on a life support system, where Alex Salmond could pull the plug any time he wants.

I don't even pretend we can occupy the Lib Dem holier-than-thou, hands-entirely-clean-and-entirely-empty-type stance. No, we are getting our hands dirty, and inevitably and totally understandably we are being accused of being just like any other politicians.

Voters tell politicians what they want through the ballot box. Constantly second-guessing them by speculating whether the parties should gang up on each other misses the point.
