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.

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.

Joining the Liberal Party was a no-brainer for me... And when you are a young man, you don't get a calculator out saying, 'Am I going to get to power?' You get propelled forward by idealism.

If there's one thing I'm not going to apologise for as the leader of the Liberal Democrats in government after 60 or 70 years of being out of government, it's that you just cannot avoid but deal with the world the way it is.

Actually, the curious thing is that the more you become a subject of admiration or loathing, the more you're examined under a microscope, the distance seems to open up between who you really are and the portrayals that people impose on you.

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.

Liberalism is a really old British tradition and it has a completely different attitude towards the individual and the relationship between the individual and the state than the collectivist response of Labour, and particularly Old Labour, does.
