Why did Labour lose the 2019 election? I think it was as easy as ABCD: anti-Semitism, Brexit, Corbyn, and demographic change.
Labour lost votes because of anti-Semitism; specifically, as far as most voters were concerned, because of Jeremy Corbyn’s lack of competence in handling the issue. For many British Jews a minority of other voters, Labour’s was a moral failing but for the majority, the damage that anti-Semitism did to Labour’s electoral prospects was mostly about how it affected the party’s perceived competence.
