Jeremy Corbyn’s brother, Piers Corbyn, a climate forecaster and fervent supporter of his brother, has issued his latest long-term prediction on Twitter: that Jewish conspirators and the Royal Family will force Donald Trump into war, just like they did to Hitler.

Piers Corbyn retweeted @whiteknight0011, a notorious neo-Nazi who declared that “They will force Trump in to war What do you think happened to Hitler? Bilderberg CIA IMF Banker Gangsters They are the problem” along with four images.

One shows Lord Jacob Rothschild, the Jewish banker and philanthropist, against the background of a Nazi flag, claiming that he controls the world. A second shows Israeli Prime Minister Benjamin Netanyahu as a puppeteer controlling ISIS through Israeli intelligence agency Mossad, orchestrating the war in Syria and Paris attacks as Lord Rothschild and the Queen look on approvingly. A third image shows the faces of supposed Jewish conspirators who run the world to society’s detriment, proclaiming: “Know your enemy”. The last image shows a family photo of the Royal Family, claiming that they are in cahoots with these Jewish conspirators in committing “the worst genocides, invasions and theft in all history.”

Piers and Jeremy have a long history of political solidarity. Piers has boasted of the family’s anti-racist credentials, but the mask is slipping. The man who now broadcasts that the Jews were responsible for the Second World War, is the same that claimed a Jewish conspiracy against his brother: when Jewish MP Louise Ellman complained of antisemitic attacks against her, Piers Corbyn accused her of using it as a cover for political attack, tweeting: “ABSURD! JC+ All #Corbyns are committed #AntiNazi. #Zionists cant cope with anyone supporting rights for #Palestine”. Brother Jeremy’s response: “He’s not wrong”.

The apple does not fall far from the tree in the Corbyn household. Jeremy Corbyn has not publicly repudiated his brother, nor any number of individuals in the Labour Party attacking the Jewish community. We would like to think it is time to start, but have long realised that any pretence that Jeremy Corbyn’s Labour is ‘anti-racist’ are now history.

What will happen next? Will Piers Corbyn say he didn’t notice the images? It’s impossible to comprehend the text without looking at the images. Will Jeremy Corbyn rally to his brother’s defence as he has before? Will they ignore the incident?

Jeremy Corbyn endorsed his brother’s views last time he alleged there was a Jewish conspiracy. Now that tweeting Jewish conspiracies is perfectly normal in the Labour Party of today, maybe Jeremy Corbyn will give his brother a peerage.
