Some are suggesting Starmer not much different than Sunak as he wants to reduce deficit and opposes most tax hikes (a few like taxing private schools and non-dom, but none that are big revenue raisers) so wondering if that is allowing Labour to win in areas wouldn't otherwise. Likewise could Greens do well in strongholds where some may feel he is too pro business and not change they want?
A Labour to Green swing in the woke strongholds could happen in the election after next, after a Labour government have started and radical types are disappointed they are not left enough.
I cannot however see it causing many or indeed any seats to elect Green MPs.
