The scuffle involved two guests at a Commons party hosted by Conservative chairman Eric Pickles on Monday night. The pair, whom Tory sources identified as journalists from the Sun and Daily Star, left the event but continued arguing about breasts in the corridor behind the Speaker's chair, at the same time as MPs were debating Africa. Spoof parliamentary correspondent Shaworth received minor injuries in the scuffle as he tried to break up the warring pair.
"They started arguing about which paper had the largest breasts, and largest number of breasts", he explained. "It started off as a bit of fun but soon escalated into a slanging match and then some pushing and shoving. I play a bit of rugby so I stepped in to break things up, and that was when the Police arrived in full riot gear."
Labour MP Kerry McCarthy wrote on Twitter that she had heard the scuffle from within the chamber, adding: "We thought it was a protest, not a punch-up."
Her message said: "Was in chamber... Much excitement, banging and shouting about tits."
The incident will raise fresh questions about security at Westminster.
Shaworth is unhurt and is continuing to provide The Spoof with up to the minute news as it happens.
