As Liberal Democrats and proponents of federalism, we must put our heads above the parapet and recapture and disseminate the true meaning of federalism. We have to win the vocabulary before we succeed in the vision.

I don't know the true meaning of happiness.

You won't catch Liberal Democrats describing trade unionists as wreckers.

I don't know the meaning of life. I don't know why we are here. I think life is full of anxieties and fears and tears. It has a lot of grief in it, and it can be very grim. And I do not want to be the one who tries to tell somebody else what life is all about. To me it's a complete mystery.

If you want more investment in education and pensions, cast a vote for the Liberal Democrats.
