A heckler with offensive blog posts to his name has been dragged from a meeting after lashing out at Jeremy Corbyn

Former SNP activist Bob Costello, 72, interrupted the Labour Party leader as he addressed supporters in Dundee.

Mr Costello was grabbed by staff after he confronted Mr Corbyn this morning, and audience members cheered as he was ejected.

He asked what the opposition leader planned to do about the "will of the Scottish people".

The man, who later identified himself as Bob Costello, a former SNP activist who is a director of Sidlaw Executive Travel in Dundee, shouted: "Is this democracy?"

It is the second time Mr Corbyn has been heckled during his two-day visit to Scotland, after a preacher with a history of posting anti-Muslim and homophobic messages implied he was a terrorist sympathiser.

After the incident today, it emerged Mr Costello ran a blog, bobsblog.scot, which in 2016 claimed the US media is "mostly controlled by Jewish money" and an "extreme, Zionist element" controls "most of the western press."

Another post on the blog from this year claimed the terror group ISIS was "at times being funded by Israel and the US".

And he featured in the Dundee Courier in 2017, defending claims he made that the Manchester terror attack was carried out by an "MI6 asset".

The Mirror spoke to Mr Costello over the phone today after ringing Sidlaw Executive Travel. He told us he was the same Bob Costello behind the blog.

He denied the remarks were anti-Semitic, saying: "Anti-Semitism is a hatred of Jewry, right? The comments I have made are not in any way anti-Semitic.

They are my opinion of what is happening, what is going on."The trope of "Jews controlling the media" is clearly included among examples in the IHRA's definition of anti-Semitism.

Asked to clarify if he thought it was anti-Semitic to say the press and media in America is mostly controlled by Jewish money, he replied: "No, no, I think it's fact."

He also said he stood by his claim about ISIS being "funded by Israel and the US".In a blog post earlier this year, bobsblog also criticised Nicola Sturgeon for attending "gay events" and "gay parades" over independence events.

Mr Costello stood by the remarks today.Another blog post this year suggested ISIS bride Shamima Begum was being treated differently because she was "coloured and Muslim".

Asked if he stood by the comments he said: "You're trying to say I'm anti-gay and anti-Semitic, is that what it boils down to?"

He added: "The comments I've made are fair comment... I don't think they're anti-Semitic in the least, no. And there was certainly no intention to be anti-Semitic because I've got a lot of friends who are Jews."

Bobsblog was set from public to private shortly after the Mirror made our phone call.

Separately the Labour Party has itself been hit by several anti-Semitism cases involving members, with party chiefs facing accusations they are too slow to act.

The Labour leader tried to hush Mr Costello when he interrupted earlier today, saying: "It's perfectly democratic when we listen to each other so I'll listen to you in a moment."

"Take your hands off me," Mr Costello shouted as he was grabbed by staff. "Is this your democracy, is it?"

Mr Corbyn launched a staunch defence: "The democracy is that we have a public meeting where we conduct it in a reasonable manner, and those who wish to say something at the end are of course free to do so.

"Democracy is not when you interrupt somebody when they are speaking."

Mr Costello asked: "I'm interested to know what you're going to do about the will of the Scottish people with regards to Article 30.

"He was ejected to cheers and claps from the audience. No question and answer session was held.

Mr Costello's questions about a section of the Scotland Act 1998, which could pave the way for a second independence referendum, came after a day of confusion over Mr Corbyn's policy on another vote.

Mr Costello, 72, told the PA news agency he left the SNP because he did not believe the party was "wholeheartedly" campaigning for independence.

Mr Costello, said: "Corbyn being Corbyn he changed his mind each hour. Yesterday he changed his mind about three times.

"I left the SNP in 2016 because I didn't believe they were wholeheartedly for independence."
