There is no reason to call a GE as we vote for a party, not a leader, and there is no way Labour will do that until they have to in two years (no party would).
They might change leaders. From a GC perspective, I would probably prefer Streeting, Burnham has been deliberately woolly on the trans issue, his statement on FWS win was a masterclass in equivocation, which just makes me think he will throw women under the bus to appease the left and the unions as required. Rainer is far too TWAW for me to even seriously consider.
