A few siren voices say Labour should just give up on the Red Wall, as it can't win it back and anyway shouldn't appeal to those values. That would be suicide.

First electorally. Let's say everything went right for Labour at the next election: SNP taking seats off Tories, Lib Dems securing LD-Tory marginals, some rapidly liberalising suburban seats going Labour.

They would still need Red Wall seats. And certainly they'd need to not lose any more. That's the only way to remove Johnson from power, let alone get a majority.

But more importantly, it's ethically wrong. You cannot allow voters left behind by the economy to be seduced wholesale into nationalist politics.

The solution to the problem is much more demanding than just waving it away. It is in finding the cultural values, as well as the economic policies, which show that the 'anywheres vs somewheres' narrative is a lie.

This is really, really difficult. That's why you will read ten thousand pieces diagnosing Labour's problem and almost none providing a solution to it.

But better to be grappling with a difficult problem which might actually solve things than with an easy one which wouldn't.
