Britain’s 260,000 or so Jews breathed a collective sigh of relief in December 2019 when Jeremy Corbyn, at the time the leader of the Labor party, suffered a decisive electoral defeat to now-prime minister Boris Johnson. For four years, the Jewish community had been tormented by Corbyn’s simultaneous encouragement and covering-up of rampant anti-Semitism in Labor and left-wing politics. As I wrote then, while anti-Semitism has long been an issue in the UK, it was under Corbyn’s leadership that it became an electoral strategy. Under him, as few as 7 percent of Jews were thought to vote for Labor in 2019, down from an even split between Labor and the Conservatives, according to a study from the Jewish Policy Institute nine years prior.
