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.
Baroness D’Souza said his behaviour was “shocking and unacceptable” and that she was referring him to the police.
“Lord Sewel has this morning resigned as chairman of committees. The House of Lords will continue to uphold standards in public life and will not tolerate departure from these standards,” she said.
“These serious allegations will be referred to the House of Lords commissioner for standards and the Metropolitan Police for investigation as a matter of urgency.”
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.
The Sewel convention, which applies to the relationship between Westminster and the Scottish government, is named after him.
He has been a member of the Lords since 1996 and is also a 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.
