Former Labour MP Eric Joyce has admitted going berserk during a House of Commons brawl, pleading guilty to four charges of assault at Westminster Magistrates Court.
The 51-year-old admitted assaulting four politicians in MPs' watering-hole the Strangers Bar in February this year.
Prosecutor Zoe Martin told the court the MP told police "you can't touch me, I'm an MP" after the court.
The former army major was arrested after headbutting Tory MP Stuart Andrew and attacking three other politicians.
Joyce, who represents Falkirk, was suspended from the Labour party following the incident which means he can no longer call himself an MP for the party.
Joyce's other victims were two Tory councillors, Luke Mackenzie and Ben Maney, and Labour whip Phillip Wilson.
He is expected to be sentenced today. Joyce can still remain as the MP for Falkirk if he is sentenced to less than a year in prison - and he has previously indicated that he wishes to remain an MP until the next general election.
The government plans to change the law to ensure politicians who go to prison for under a year will be subject to an automatic recall election.
