I wonder if the advice of Defence Secretary Ben Wallace to MPs to stay away from the Commons bars would help address the sleaze crisis at Westminster.

The various watering holes around the Palace of Westminster have been the scene of infamous fracases over the years (two SNP members coming to blows over a party aide, a Labour MP headbutting a Tory MP in Strangers’ Bar), salacious exploits too many to mention, and career-ending indiscretions.

“We’ve seen fights, we’ve seen sexist comments, we’ve seen propositions,” said Wallace. Quizzed on the radio on Thursday over claims by two female Tory MPs that they had seen a male colleague watching pornography on his phone in the House of Commons, he said there was a “problem with the overall culture” in parliament.
