According to an article posted by a Facebook group for UK Independence Party (UKIP) supporters, Jews are conspiring to subvert British democracy and engage in “treason” by undermining ‘Brexit’, Britain’s exit from the European Union.

Posted by ‘The UKIP Society’ Facebook page as a “very interesting observation”, the article attempts to expose a Jewish conspiracy by highlighting the people involved in Thursday’s High Court decision against the Government’s proposed Brexit process whom the author suspects of having Jewish heritage.

The post has been shared dozens of times, including by the ‘UKIP Hertford and Stortford’ Facebook page, and has attracted appalling antisemitic comments.

Facebook user ‘Darren Brown’ observed: “Rothschild. Soros. Rockefeller. Warburg. Du Pont. Morgan. ALL JEWS. ALL central banks are owned by Jews. It isn’t a coincidence they run the world.” Facebook user ‘Theresa Guilfoyle’ added: “No doubt. Rothschilds and rich bankers right behind it.”

Facebook user ‘Sue Thorpe’ complained: “Who else is going to poke their nose into our business? After what we did for the Jews during WWII they have a short memory! Just leave us alone to get on with our own lives!”

Facebook user ‘Maggie Tucker’ was sceptical that Jews oppose “British rule” but added “Mind you these Jews are all wealthy and that makes a difference now as in the past.”

Facebook user ‘Peter Baker’ earned a number of likes with his comment: “Tell the to keep their big noses out it’s not their business.”

Facebook user ‘Fred Matthews’ echoed Nazi propaganda, simply writing “Parasites”. ‘Jim Dunn’ contributed his solution: “Open up Hitler’s gas chambers the Jews know the way in”.

Facebook user ‘Nik Schofield’ was so outraged that he wrote: “Zionist c**ts these are the worst ya dont have to be Jew to be Zionist but all Zionists are Jews end of”.

According to the International Definition of Antisemitism, “Making mendacious, dehumanising, demonising, or stereotypical allegations about Jews as such or the power of Jews as collective — such as, especially but not exclusively, the myth about a world Jewish conspiracy or of Jews controlling the media, economy, government or other societal institutions” is antisemitic.
