One thing I have frankly decided is that when it comes to political reform we have two conservative parties in British politics. Both the Labour and Conservative parties have constantly and repeatedly failed to honour promises they have made about reforming, cleaning, modernising our clapped-out system.

The Liberal Democrat Party and the Conservative Party come at things very differently when it comes to Europe. When it comes to political reform, we have a much greater tradition in the Liberal Democrats of social justice and fairness than the Conservatives do.

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.

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

Grown-up politicians talk to each other across party lines. Over the last few weeks I have had lengthy conversations with Ed Miliband, David Miliband, with Tony Blair, with Peter Mandelson... talking about Europe, talking about political reform.

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.
