A day later, he replied to a post by former UFC fighter Jake Shields, who has repeatedly expressed antisemitic views, that claimed that the Holocaust’s death toll is “made up”.

“Six million Polish people, including some Jews. They always use Poles to make up the number. And on top of it they claim Poles were killing. Just sick,” Mitula commented.

Mitula, originally from Szczecin in Poland, also made a post, first reported by the Manchester Mill, featuring a racial slur against black people, and another that suggested that 60 to 70 per cent of transgender people are paedophiles.

The account in question now appears to have been deleted.

A spokesperson for the Campaign Against Antisemitism said: “These are the sorts of putrid comments one might expect to see in the dark corners of the internet. Instead, they are reportedly attributed to Adam Mitula, Reform UK’s interim campaign manager in Tameside.

“Disgraceful remarks like these require a full explanation and, if found to be true, immediate action from Reform UK.

“Antisemitism must be rooted out in every political party.”

Reform UK leader Nigel Farage has himself faced backlash recently for anti-Jewish comments he allegedly made when he was in secondary school.

He later apologised, saying: “If they genuinely [was upset] then that’s a pity and I’m sorry, but never, ever did I intend to hurt anybody”.

The recent revelations about Mitula come less than a week after Reform UK launched its new Reform Jewish Alliance (RJA).

The launch event took place last Tuesday at London’s Central Synagogue and was attended by around 300 people.

Mitula, Goodwin and Reform UK did not respond to the JC’s requests for comment.
