A leading comedy agent “screamed” at a Jewish Edinburgh Fringe performer that Jews smeared Jeremy Corbyn and exaggerate antisemitism.

Bennett Arron, who has been hailed as the “Welsh Seinfeld”, said what had been a “wonderful” experience at the world's biggest arts festival was spoiled when he was subjected to a hateful rant on Sunday night.

After a highly successful run that saw him perform to sell-out crowds, the stand-up went to a bar with his family to celebrate.

When a comedian friend asked if his agent - who allegedly represents multiple well-known comedians - could join, Arron said he could.

“Within a phenomenally short space of time [the agent] started talking about Jews,” he told the JC.

“My friend - who’s a client - mentioned Jeremy Corbyn, obviously they'd spoken about him in the past. 

“That seemed to be the catalyst for him to say, ‘why did Jews exaggerate antisemitism?’ out of nowhere.

“[The agent] said there was no proof [of Corbyn’s alleged antisemitism]. I said this isn’t the right time to talk about this - my friend was trying to calm him down.”

Despite this, Arron said, the agent would not stop shouting that Jews “should never have been given Israel”.

He said: “It was sort of coming from nowhere - it was so loud, so angry. 

When Arron told him he thought it was “not the time” to discuss the topic, the agent is said to have replied, “see they always do this".

“Once it started it was a torrent,” Arron said. 

“He was shouting, it was aggressive. I probably would have dealt with it in a different manner if it was calmer. He just wouldn’t stop. He wouldn’t listen to anything I was saying.”

Arron added: “My family were taken aback. Eventually I decided we should leave. 

“I went to the loo, then said to the family we should leave.”

His relatives, he said, were in “shock” at what they had witnessed.

“They were just in complete bewilderment. They had never seen anything like this before.”

On Monday morning, the agent - who Arron will not name because he does not want to damage his client’s careers - contacted him after seeing a post the comedian had made on Twitter/X about his rant.

During the ensuing phone call, the agent denied that he had accused Jews of smearing Corbyn or exaggerating antisemitism, and said he would “never” make such claims, Arron said.

Though he has experienced casual antisemitism in the comedy industry before, Arron said, this was a new extreme.

“People I’ve worked with have made comments. I did realise [British comedy] did have that undercurrent. 

“Now they feel that they can say what they want to say.”

Despite the agent’s outburst, Arron said, he will take his hit show, Loser, on tour around the UK and return to Edinburgh Fringe next year.
