Sonia Sodha of The Observer assesses the latest developments at Westminster. Following the Prime Minister's speech on global insecurity she speaks to former Conservative Defence Secretary, Sir Liam Fox MP, and former Labour International Development Secretary, Douglas Alexander. Theo Bertram, director of the Social Market Foundation and a former Labour adviser, discusses whether election 'pledge' cards are a good idea following Sir Keir Starmer's campaign event this week. After a knife-edge vote on excluding from Parliament MPs accused of serious offences, Sonia speaks to Liberal Democrat Chief Whip Wendy Chamberlain MP and Conservative MP Nigel Mills. And, after claims a Liberal Democrat candidate was deselected because of his Christian faith, Sonia brings together the Rt Rev Nick Baines, Bishop of Leeds, and Polly Toynbee, journalist and vice president of Humanists UK, to discuss whether Christianity and modern politics are compatible.
