There's been a lot of Left campaigning against Labour, especially around Palestine/Israel. These votes predominantly going to independents and Green. Simultaneously, there's the right (and left) campaigning against Conservatives, with bites being lost mostly to Reform and abstaining. It's been a weird one.

Both left and right don't feel their supposed parties represent them. Seeing the two parties as a choice between Balirite Blue or Blairire Red.

But yeah you're right, this Labour win would be less than what labour under Corbyn got when he lost. But there was more of a united front against Labour then.
