Tony Blair and Gordon Brown committed to John Major's spending envelopes in 1997. No-one said that Tony Blair and John Major were identical. This happens quite often that parties actually, despite all the sound and fury, agree on the overall need to make sure that we live within our means as a country.

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.

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.

I don't want to clip on the armour every morning. I've seen some politicians do this and they get a bit mangled and bitter. I just refuse to do that. I refuse to be angry or bitter or complain, and I remain open. I may sometimes be a bit too open but I'm not going to change that one bit.

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.

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 lead a particularly Bohemian existence. The main criterion for me is not to be judgemental of other people so long as what they do is not harmful or offensive to others.
