What happens in the Strangers’ Bar stays in Strangers’  Bar, or so they like to think. That rule goes out the window though if you’re a Labour MP who gives a Tory colleague “a Glasgow kiss”. Labour’s Eric Joyce was nicked last night after apparently headbutting Tory MP Stuart Andrew.

Witnesses tell Guido he “just kicked off” and start flailing shouting “There are too many Tories in the bar”. Tory councillor Luke MacKenzie got punched while trying to break things up. Guido is trying to work out what triggered it all and you can whisper what you know here.

Aside from one too many taxpayer subsidised pints of course…

UPDATE: Joyce wasn’t the only politico arrested last night. West Midlands MEP Nikki Sinclaire, who was forced out of UKIP, was arrested in Birmingham for conspiracy to defraud the EU Parliament.
