I sometimes can't get over how awful Starmer's delivery is, right up there with adenoidal Rachel, whose voice is bloody awful, overly defensive under pressure often veering into screechy Estuary, I find listening to her for any length of time such as when she was delivering the Budget quite painful, compared to Kemi's well modulated vowels. Starmer on the other hand sounds like an automaton, so much so, I can't help pondering is he actually real? or a digital manifestation. He's certainly no orator. However, better the automaton you know than one that could be worse.
My choice for an alternative leader would be Shahbeena Mahmood who appears to have some grit and isn't mired, as far as we know, from tax evasion or any other scandal.
