The Labour Party has become consumed by collective bile towards... the Liberal Democrats. That portrays a rather nasty arrogance.

Most of what needs to be changed in the euro zone can be done without treaty changes. The demand for treaty change is as political as it is legal and I don't think it's going to happen soon.

Growth that lasts does not threaten our children's future. It recognises that our planet is a gift that must be cherished. That tomorrow is our responsibility as much as today.

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.

After the economic 9/11, we will face a new world order.

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.

The Conservative Party is not honouring the commitment to Lords reform and, as a result, part of our contract has now been broken. Clearly I cannot permit a situation where Conservative rebels can pick and choose the parts of the contract they like, while Liberal Democrat MPs are bound to the entire agreement.
