The left faces a challenging battle in the fight against allegations of antisemitism over coming months. The attacks did not end with Labour’s election defeat or Jeremy Corbyn’s departure as leader. Indeed, the probusiness and pro-imperialist wing of the party is stepping up its onslaught. This is an attack that extends to the entire left. A huge responsibility will fall upon the left to face this onslaught in a principled fashion, and to expose the false conflation between anti-Zionism and antisemitism that lies at the core of the allegations.
