The price of alcohol sold inside the Houses of Parliament is "under review" after police dealt with an altercation inside a Palace of Westminster bar.
At 6.30pm on Tuesday (December 5), police were called to a courtyard near the Sports and Social club and arrested a 57-year-old man on suspicion of causing grievous bodily harm and affray.
The man was taken to a central London police station.
Following the incident, Tory MP Philip Hollobone asked the House of Commons Commission what was being done to prevent such incidents in the future.
In response, chair of the Commons Commission and Liberal Democrat MP Tom Brake said: "There is no direct financial subsidy on alcohol sales served in the House of Commons.
"Alcohol is sold in House of Commons bars, some catering venues and in banqueting and events, achieving a gross profit margin of around 69%, this profit of around a million a year helps to offset the total cost of catering.
"He may be aware of the incident a couple of days ago in relation to the Sports and Social Club and that is something that is run by the House of Lords.
"There is an investigation under way into that and clearly this is an issue that is under review, I think, for the reasons he has set out."
According to a House of Lords Spokesman, the bar has been temporarily closed, the spokesman said: "Following an incident on the parliamentary estate last night involving two parliamentary staff, after leaving the Sports and Social Club Bar, an investigation is under way and the bar will be temporarily closed until that investigation is complete."
