No restrictions on religion in the UK for anybody except the Royal Family and ministers of their various churches, and that's as it ought to be. It was an issue in 1839, not now. We've had a PM, Disraeli, of Jewish ancestry. But it's typical of Blair's rather sneaky way of doing things- he wouldn't declare himself openly while he was hoping to garner a few extra votes, just a few people maybe might be put off. Everything, including his immortal soul, is subordinate to PR.

He's also made a point of favouring faith schools while in office, though I think that's more a matter of getting schools out of local democratic control, and into the hands of a private quango.
