Ed Miliband's invitation to the new Archbishop of Canterbury was a mistake and a wrong turning in British politics.

If this election has told politicians one thing, it should be that they should listen to the voters and not to the religious lobbyists who are trying to write their doctrines into law.

The Tories plan to use the upcoming Corby by-election to "road test" an appeal to the "faith vote". Terry Sanderson questions whether a religious voting bloc even exists in the town – or anywhere in Britain for that matter.

If Santorum's tactic of overstating religion pays off, can we can expect a similar ratcheting up of the Pickles/Warsi "Britain is a Christian country" message here?
