Hard to know.
Despite the incredible levels of incompetence and disregard for the rules shown by this current lot I still wouldn’t rule out a Konservative win at the next election. Years of underfunding education, allied to an almost completely right-wing press, and alongside an inherent English desire for toffs to run the country, are a mix that will be hard to overcome. Starmer doesn’t exactly set the world on fire either.
That said, by next winter the average voter is going to be in the midst of a personal financial brick-storm the likes of which none of them will have lived through before, so we will see.
We can but hope.
