We are keen to stress that a strong euro zone is good for a strong United Kingdom. It's not for us to write the changes that the euro zone needs to embark on.

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.

Nothing will do more damage to the pro-European movement than giving room to the suspicion that we have something to hide, that we do not have the “cojones” to carry our argument to the people.

My head spins. One moment I'm told I'm too edgy, then people say I'm too angry, then that I show too much passion... make your minds up.

Any government, of whatever composition, needs to mobilise opinion way beyond its own ranks in order to do the difficult things that it does.

We need to teach our kids, because there is such a celebrity culture at the moment, that however rich you are, however famous you are, however glamorous you are, everyone has to live by the same rules.

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.
