Maybe I'm an outlier here, but I don't think Starmer should go at the moment. There was a fuck up, possibly his, but has he swept it under the carpet like the previous 3 PMs? No. Has he tried to hide it? No. Is he passing the back? No.
What he is doing is being open and transparent. We are all human, and we are all capable of putting our trust in the wrong person, particularly is Starmer is being honest when he says Mandelson lied during vetting. Our parliament was built around honour, and honesty, and has seemingly little recourse for when these values fail
I'll wait for the documents, and the evidence and the facts and next steps before calling for his head.
