I think this is what's shocked me, there hasn't been a sudden swing to the Left, it's that the Conservative vote has been massively impacted by support for Reform. Ironic really, so many pp voting for a more right wing party than the Tories and Labour get in!
I think Labour will have to be very careful, they don't have the mandate they think they do. And think they've been handed a bit of a poisoned chalice, considering the mess this country is in. Will be interesting seeing how this plays out...
