The discussions to form a new government dominate the news agenda - former Conservative Defence Secretary Michael Portillo tells Nicky Campbell that a deal has to be concluded as soon as possible to keep the markets stable. The ex-leader of the Liberal Party, Lord Steel, says that there's no rush and that a long-term deal is the key. Elsewhere a listener who said he couldn't understand what was funny about terrorism reviews the new film about home-grown jihadis Four Lions, and the librarian of the Royal Society explains to Shelagh Fogarty why a piece of of wood is about to be sent into space. And there's coverage of Chelsea winning the Premier League, including from the club's Chief Executive Ron Gourlay who says that their victory was due to the club being a tight unit that wasn't undermined by captain John Terry's off-field troubles - and that he's a Rangers fan.
