After the remarkable scenes in the House of Commons as MPs voted to make Tory MP John Bercow their new Speaker, Andrew Neil and Anita Anand look at what changes he is planning for the way Parliament works. He says he will follow a reforming agenda, but can anything he does restore trust in our politicians after the expenses scandal? There is also the latest on Gordon Brown's Iraq Inquiry. Having insisted its proceedings would be conducted in private, it is now clear that the inquiry chairman Lord Chilcott will hold at least some of his hearings in public. As David Cameron and Nick Clegg meet Lord Chilcott, Anita and Andrew ask whether their concerns about the inquiry have now been met. The former head of the civil service Lord Butler discusses how Whitehall prepares for a possible change of government, and the Labour peer Lord Puttnam talks about trendy teaching methods.
