Gordon Brown has made a speech in Elderslie today in a joint event with local Labour candidate and shadow foreign secretary Douglas Alexander at Elderslie Village Hall.

Mr Brown, the Former Prime Minister was speaking to Labour supporters in the village hall said that the SNP wanted to win seats in the House of Commons “not to deliver social justice” but to “deliver” chaos and constant crisis”.

He referred to a video posted on YouTube last month, understood to have been filmed in November last year, featuring SNP candidate Mhairi Black.

He said: “There is an SNP candidate in this constituency. She says vote SNP, get SNP MPs at Westminster and we will twist their arms and get another referendum.

“Remember what the SNP used to say – the referendum was once in a generation, then it changed a little to once in a lifetime, then it was once every 15 years and now when you ask Ms Sturgeon about this her answers are all evasion. She cannot give a straight answer to the question.”

Responding to Mr Brown’s comments, an SNP spokesman said Ms Black had been making the point that “if the people of Scotland do in the future decide there should be another referendum the Westminster establishment must not stand in their way.”
