Belinda Dixon looks at religion and ethics

A week a lesbian couple - both Christians - will take the first step towards challenging the right of the government to refuse full marriage to gay couples. We'll hear more.

And the organiser of the annual Commando Challenge (which a team from BBC Radio Devon recently took part in to raise money for the BBC Radio Devon Air Ambulance Appeal), will be joining Belinda in the studio.

Alan Hardy will be talking about the challenge - and reviewing the stories making headlines in the Sunday papers.
