The Jewish organiser of an anti-Ukip demonstration claims he has received death threats on social media after being labelled ‘scum’ by Nigel Farage.

Dan Glass led protests outside Mr Farage’s local pub in Downe, Kent on Sunday where the Ukip leader was eating lunch with his wife and two children.

Mr Farage said the demonstrators forced him and his family to flee the pub, and had jumped on the bonnet of his car as he drove away.

He told reporters: "I hope these 'demonstrators' are proud of themselves.

"My children were so scared by their behaviour that they ran away to hide.

"These people are scum."

But Mr Glass, 31, said he was not aware that Mr Farage’s family was present.

He said: “I didn’t see him with any children.

“All we saw was him running out of the pub pushing through our line and shouting scum.”

Mr Glass said that the point of the protest was not to target Mr Farage but “to take a group who represent migrants, gays, breastfeeding mums and the disabled to show to his pub and celebrate them.

“There were local members of his community there too who didn’t want to be tarnished with the same brush as Ukip.

He said that when the protesters – who included a Holocaust survivor - realised Mr Farage was in the pub “some broke off to go and challenge his views and that is when he came running out.

“No one saw any children and he ran away before anyone got a chance to speak to him.”

In response, a UKIP spokesman said: “Dan Glass’s comments about the event are contradicted by independent journalists on the scene who recognised the bullying and threatening nature of the event. Given that Nigel, his wife and kids were trying to enjoy a quiet Sunday lunch, the bullying nature of this whole episode reveals a real darkness behind a movement which would otherwise allow you to think it is open and tolerant. What ever happened to Voltaire?"

Mr Glass, who set up Holocaust memorial group Never Again Ever, said: “We wanted to challenge the otherness he promotes and that’s why some went to talk to him.”

He added: “And of course we are against people jumping on his car, that is not what we are about, but I do understand why people are angry.

Mr Glass said his Jewish roots were his motivation for opposing Ukip.

He said: “All four of my grandparents are survivors. It is engrained in me to stand up against injustice.

“We had survivor Ruth Barnett there who gave a speech and the whole day was a celebration of diversity and culture.”

The campaigner said since Mr Farage accused his group of scaring his children he has received death threats and has had his personal details posted on far right website Britain First.

Mr Glass said: “I’ve had messages from people threatening to kill me. My photo is on Britain First and my Facebook has been inundated with messages from people I don’t know.

“They have left homophobic and antisemitic messages saying they support Farage and I should ‘watch out’.
