The Greens were busy telling Labour voters they were the main challenger to Reform, which they either were or it was a self fulfilling prophecy.
The Tories never mentioned in their manifesto that they would abolish secondary voting in elections (which failed to dislodge Sadiq). So no reason why Labour shouldn't introduce it.

Not just "Labour factions". This paper is pretty keen to push Labour into a "leftward pivot" as well, despite the pretence that it's just reporting events. Given the reaction to the SEND announcement, Labour might think there's no point in putting taxes up to spend on vulnerable people.
