In an op-ed for The Guardian, former Canadian Prime Minister Stephen Harper warned against the rise of anti-Semitism in the UK and Europe.

In reference to the controversial far-left leader of the British Labour Party, Jeremy Corbyn, the former Prime Minister wrote: "Jeremy Corbyn- a man who lays wreaths at the graves of anti-Semitic terrorists, and then thinly papers over his actions with nonsensical hair-splitting. Mr. Corbyn's comfort in the company of anti-Semites and other extremists who, he calls "friends" speaks for itself. While he claims to embrace such individuals in the name of "peace" it is a peace that only ever involves the enemies of the West generally and of the Jewish people specifically.

He also wrote: "It is time to strip away all the rhetoric and rationalizations. Mr. Corbyn and his allies hate Israel uniquely and obsessively. Under his leadership, Israel- and thus any Jew daring to identify with it- will face relentless slander. He, and those who share such malignant views, must be exposed and opposed at every direction."
