Lord Sewel – should he stay or should he go? Lembit Opik and @Kevin_Maguire discuss. #BBCNolan

Should he stay or should he go? The senior peer Lord Sewel has been urged to resign from the House of Lords after he was filmed allegedly taking drugs with prostitutes. Lord Sewel, who is yet to comment on the claims, has already quit as Lords deputy speaker and chairman of the Lords privileges and conduct committee. He could also face a police inquiry over the Sun on Sunday's footage.

The BBC has spoken to sources who say the peer has indicated he does not intend to quit.

But should he or has he suffered enough?
