Theresa May used her first campaign visit to Scotland yesterday to dismiss Nicola Sturgeon’s claim that she would agree another independence referendum if the SNP won on June 8.

The Prime Minister refused to support Ms Sturgeon's suggestion that her opposition to holding another vote on breaking-up Britain will “crumble to dust” if the SNP take most seats north of the border.

Mrs May instead said she would only allow a new vote if there was clear evidence that the people of Scotland wanted one – something not currently the case according to polls.
