We need to reach out to small 'l' liberal voters who have a modern outlook on life, who want a party that is hard-headed on the economy - more credible on the economy than Labour - but more socially progressive and fairer than the Conservatives.

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.

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.

I say this as a young dad seeing children going into primary school: I don't think we should underestimate the formative effect on a child of those first years in primary school.

If the euro zone doesn't come up with a comprehensive vision of its own future, you'll have a whole range of nationalist, xenophobic and extreme movements increasing across the European Union. And, frankly, questions about the British debate on EU membership will just be a small sideshow compared to the rise of political populism.

The Liberal Democrats will add a heart to a Conservative government and a brain to a Labour one.

I think it is a simple statement of principle that in a democracy you should make your MPs work harder for your vote and try and get at least majority support in their local area, and that in a nutshell is what AV does.
