The Business Secretary, the senior Lib Dem Vince Cable, has been given a tough time in the Commons over the behaviour of the banks and his secretly-recorded comments to undercover reporters before Christmas. Labour MPs also voiced their concerns over the Government's switching of responsibilities for Rupert Murdoch's media expansion plans from Vince Cable's Business Department to the Department for Culture, Media and Sport. MPs complained that they didn't know who was responsible for what. Today in Parliament, with Rachel Byrne, reflects these stories. Also on the programme: * Kristiina Cooper reports on MPs' reaction to a newly published document that's been called the closest thing to a written British constitution. * Viv Robins reports on peers' forthright views on the role that Turkey could play in the future of Europe. * Simon Jones reports on claims that standards of behaviour in the House of Lords have fallen. One peer said the Lords was in danger of adopting 'the bad habits of the Commons'.
