Yes, I've seen these very talking points in the Express, Harvey Jones I think, and then percolated out into other channels. Of course Rayner would argue for example that the WFA situation is not at Labour's door and that it's a bitter pill resulting from the delinquency of the previous government. She'd have similar rebuffs for pretty much everything you've levelled at her.
But that's not really my point. Taking a step back, none of these things strike me as a smoking gun for the level of character assassination and opprobrium that she in particular receives; especially relative to our recent political history and the collapse of standards in public life during the last few parliaments. I don't think I'm really any the wiser why she elicits the level of vitriol she does from certain quarters, but thanks for responding to my enquiry.
