On 'All Things Considered' this week (Sunday 18 April at 8.30am, repeated on Thursday 22 April 22 at 5.30am) Roy Jenkins and guests discuss the relationship between religion and politics.

So how will you decide who to vote for? If you're already floundering under the deluge of leaflets from the parties, saturated by news bulletins and election specials, here's something which might just make your day. Or not.

All the main churches and many other faith groups have published election guides, key questions for candidates, background briefing notes on everything from youth crime to global peace and security.

How are we expected to pick our way through all this and make up our minds? What difference should faith make to the way we vote? And are we more likely to trust a politician who professes to be a religious believer?

Roy Jenkins is joined from London by Jonathan Bartley of the religious think tank Ekklesia, and by Dan Boucher director of parliamentary affairs for the Christian campaigning charity Care.

In Birmingham is the Islamic scholar Mashuq Ally and with Roy in Llandaff is Aled Edwards, chief executive of the Welsh ecumenical body Cytun, Churches Together.
