While we remain a nation decisively shaped by religious faith, our politics and our culture are, in the main, less influenced by movements and arguments of an explicitly Christian character than they were even five years ago. I think this is a good thing - good for our political culture.

Once the cry and the cause of a generation of progressives to make America safer, fairer and cleaner, 'regulation' is now a dirty word in our politics. Even Democrats are quick to talk about cutting regulations Republicans hate them with - how to put it? - evangelical fervor.

Whether one believes or not, religion is as real a force in the life of the world as economics or politics, and it demands fair-minded attention. Even if you think the entire religious enterprise is at best misguided and at worst counterproductive, it remains vital, inspiring great good and, sometimes, great evil.

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 didn't come into politics to change the Labour Party. I came into politics to change the country.
