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 care more about getting this right [NHS reform] than I do about getting it done.

I didn't become leader to transform the Liberal Democrats into an enlarged form of the Electoral Reform Society. It's not the be all and end all for us. There are other very, very key ambitions in politics, not least social mobility and life chances, that I care about as passionately if not more.

I totally accept that it's a legitimate criticism that when you are involved in the day-to-day scrum of government that what can get lost is the narrative, the hymn sheet the song that inspires and lifts people's sights.

Do I get up every morning and ask: am I doing the things that I believe in and am I doing them for the best possible motives? Yes. Unambiguously yes.

The caricature of what George Osborne is doing on the fiscal side is absurd. If you read some of the commentary, particularly from the left, you would think he was turning the clock back to the 1930s.

I think that the days when newspaper barons could basically click their fingers and governments would snap to attention have gone.
