Of those who voted Labour in 2017, just 51% would vote Labour today. The first is demographic (older, mainly leave, voters dying while overwhelmingly pro-remain teenagers reaching voting age). The second is Labour voters changing their minds – especially in the party’s northern and midlands heartlands. Last month’s election provided the gust of wind to detach them. The consistent signs from the polls since last summer, and from last month’s election, are that voters are increasingly polarised on Brexit.
