Lord Sewel is facing a police inquiry after quitting as House of Lords deputy speaker over a video allegedly showing him taking drugs with prostitutes. Lords Speaker Baroness D'Souza said he had also quit as chairman of the Lords privileges and conduct committee in the wake of the Sun on Sunday's story. The footage showed him snorting powder from a woman's breasts with a 5 note. In the footage, Lord Sewel, who is married, also discusses the Lords' allowances system. As chairman of committees, the crossbench peer also chaired the privileges and conduct committee, and was responsible for enforcing standards in the Lords. The role, which comes with an 84,500 salary, meant he was in charge of proceedings when the Lords considered a bill at committee stage, and was automatically made a deputy speaker. Lord Sewel served as a minister in the Scotland office under Tony Blair's Labour government. He has been a member of the Lords since 1996, and is a former senior vice principal of the University of Aberdeen. In a recent blog for the Huffington Post, he said the Lords had taken "major steps" to "protect its reputation and punish misconduct by its members". He highlighted the new power of peers to suspend for any length of time or expel a member who had misbehaved.
