There's a whole litany of letters in today's Guardian (they're on the website) lamenting Starmer's lack of leadership. Here's an example which particularly chimes with me:

Labour’s Brexit policy is not pragmatic, it’s cowardly. Keir Starmer is so afraid of upsetting the “red wall” reactionaries that he surrenders to them. That isn’t leadership – it’s followership, and the country deserves much better from its main opposition party. If he can’t face rejoining the EU, he could at least propose the only pragmatic solution: rejoining the single market in order to alleviate the worst of the damage that Brexit has inflicted on our economy.

The last one wishes the Durham police well - and it's from a Labour supporter.
