Starmer's on borrowed time, IMHO.
I don't think anything he says or does now will cut through. He made the Island of Strangers speech. He is chasing the Reform vote.
I think Starmer should call a snap GE. Lance the boil. Let the UK decide once and for all what it wants to be.
If in the very unlikely event Reform got in (and it isn't likely to as it wouldn't be anywhere near ready for a GE right now and it has some competition for far right votes in the form of Advance), it would collapse quickly. It would be horrible, but would be the end for Farage.
If Reform lost, it would also be the end for Farage. Starmer's authority would be re-established and maybe he and the Labour party would find their backbones and actually be the Labour party instead of pandering to the far-right.
