A beer called Top Totty has been banned from a parliamentary bar because its pump plate image of a half-naked lady offended women MPs.
Shadow equalities minister Kate Green said she was left "disturbed" after seeing the ale in a popular House of Commons watering hole and demanded bar staff remove it from sale.
Within 90 minutes, House authorities ordered the beer withdrawn after Commons' Leader Sir George Young told MPs: "Action will be taken."
The row sparked a debate among Tweeters who tried to outdo each other with new names for the offending beer.
Bitter Commons Row
The bitter backlash developed after Green told the Commons: "I was disturbed to learn that the guest beer in the Strangers' Bar is called Top Totty and there is a picture of a nearly naked woman on the tap."
She called for a debate on "dignity at work in parliament" and asked Young to back her demands for immediate withdrawal of the beer.
Top Totty's Stafford-based brewer Slater's describes the ale as "a stunning blonde beer, full-bodied with a voluptuous hop aroma".
"I would very much regret it if any offensive pictures were on display in any part of the house," Young told MPs.
Speaker John Bercow's wife Sally, who last year posed in just a bed sheet for a photoshoot, took to Twitter to vent her anger at the beer.
She wrote: "Cannot *believe* that there's a beer called Top Totty on sale in the Commons! Outrageous - does Mr B know?"
The beer's withdrawal will come as a blow to Tory MP Jeremy Lefroy, who organised for Top Totty to be sold in Strangers'.
Announcing its introduction as the bar's guest ale, the Stafford MP said: "This is a great opportunity to showcase a fantastic and award-winning beer.
"Slater's Brewery produces many popular beers and it is great to be able to share some of Staffordshire's finest produce with colleagues in Parliament."
