Protesters yelled at James Cook, BBC Scotland’s editor, as they demonstrated outside the Conservative hustings in Perth on Tuesday, with calls of “traitor”, “scumbag rat” and “liar” heard.

On Wednesday, Scotland’s First Minister hit out at the independence backers who abused him.

“Hurling abuse at journalists is never acceptable,” the SNP politician tweeted.

“Their job is vital to our democracy and it is important to report and scrutinise, not support any viewpoint.

During the video, which was filmed by protesters, Mr Cook was asked how long he had been in Scotland.

“I’ve been in Scotland my whole life,” he told the woman, who was asking about the Claim of Right, a document which dates back to 1689.

“I’m not going to be starting asking you how long you’ve been in Scotland, I think it’s a bit of a rude question.”

After yells continued from the crowd, Mr Cook said: “It’s a waste of time. I’m very much trying to have a civilised conversation with you, in our nation, which we share, but I can’t have a civilised conversation because this gentleman calls me ‘traitor’ and ‘scum’ and screams me down.”

At the protest, there were also reports of abuse being hurled at Tory members as they walked in, as well as eggs being thrown.
