I’d say it’s debatable that they are centre-left. I know they are labelled that everywhere, but Starmer has made notable shifts to the right (or at least towards centre) from the slow left movement since the very much centre-right New Labour of Blair.
It was disappointing that they agreed to the coalition, but at the time I remained hopeful. Then conceding *every single *manifesto pledge and party stance to the Conservatives, without any sort of resistance, just so they could stay in some sort of power, was absolutely unforgivable.
