The MP convicted of assaulting fellow politicians in a House of Commons bar has admitted to being involved in around 100 fights in his life, and boasted that he's never lost a single one.

Eric Joyce was suspended from, and later quit, the Labour Party after a fight in which he head butted Conservative MP Stewart Andrew and attacked several others.

He was given a 12-month community order and a fine of £3,000 by Westminster Magistrates' Court in March, as well as a ban from entering pubs and licensed premises for three months.

Following his conviction he expressed his "personal shame" at his actions and apologised to those he had hurt.

However in an interview with the Mail on Sunday, Joyce recounted the attack and gave readers lessons in how to best perform a headbutt.

"I saw red. I thumped them with my fist and my head – not with massive viciousness, just enough to sting them," he said.

"They were quite genteel people. It was more like me marauding. It wasn’t a fight, it was me on the rampage."

The former Army officer had some advice for people looking to take matters in to their own hands as he had: "You aim for the bridge of the nose because it is very soft. Then hit them. Just a couple of times."
