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.

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.

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.

If you scratch below the surface and ask what really makes me tick, it's the liberalism of trying to promote freedom and opportunity. Promoting social mobility is one of the keys to that.

Our Sheffield and London homes are worth well over a million but the bank owns most of them - we are mortgaged up to the gills.

I genuinely believe that we will look back on today as a landmark for equality in Britain ... No matter who you are and who you love, we are all equal. Marriage is about love and commitment, and it should no longer be denied to people just because they are gay.
