SNP MP Steven Bonnar has apologised after a heated altercation with a neighbour.

The dispute involving Mr Bonnar and an unidentified neighbour was over a Celtic FC flag in the window of the MP’s home in Uddingston, South Lanarkshire.

The two men challenged each other to a fight during the row, which was caught on video and uploaded to YouTube.

The footage shows Mr Bonnar being asked by the neighbour in relation to the flag: “Is that necessary?”

Mr Bonnar is then seen crossing the street to repeatedly ask his neighbour: “Is what necessary?”

The Coatbridge, Chryston and Bellshill MP then further asks: “What’s it got to do with you what’s in my house?”

Mr Bonnar is repeatedly referred to as a councillor, to which he replies: “I’m not a councillor, I’m an MP.”

The MP can then be heard in the footage referring to his neighbour as a “headcase”, before saying he would fight the man “any f****** time”.

In a statement yesterday, Mr Bonnar apologised and said he had been “drawn into” the argument.

He said: “I regret being drawn into a dispute with a neighbour and reacting hastily to comments made.

“I apologise for my language and behaviour, and for any upset caused.”
