A GLASGOW MP has accused a veteran Labour left-winger of swearing at him in the House of Commons chamber.

Stewart McDonald, Glasgow South SNP MP said Dennis Skinner called him a “piece of s***” during a parliamentary debate.

Mr McDonald told of the abuse on twitter and said Mr Skinner had become a “thug”.

He said: “A new parliamentary habit seems to be forming, whereby any time an SNP MP sat behind Dennis Skinner verbalises any frustration about what Jeremy Corbyn says, he angrily turns round to tell us off.

“He has just turned round and called me a ‘piece of s***’. He has become a thug.”

The Labour politician who has been an MP since 1970 nicknamed the Beast of Bolsover for his often savage attacks on Tory MPs and governments.

Later responding to someone defending Mr Skinner who told Mr McDonald to “respect your elders, their words often contain wisdom” the MP replied “It contained neither respect nor wisdom. “He is a romanticised thug.”

Mr Skinner regularly sits on the front bench in the commons but across the aisle from the Labour front bench and usually has SNP MPs including Mr McDonald directly behind him.

He was involved in a spat with the SNP in 2015 when the party, with 56 MPs wanted to occupy the front bench.

Mr Skinner however refused to move and made sure he was in the Chamber every morning at 8am with a prayer card which entitled him to the seat for the rest of the day.

He has been suspended many times for his language in the Commons amost recently for calling then Prime Minister David Cameron "Dodgy Dave."
