there's a core of truth there, the stuff about Rishi being uninterested in everything not his next job, mired in dither and unable to take decisions, but jeebus is she mental and sure of her main character status 

Sails, she didnt quit though.  Bizarrely she is getting credit on the right for some sort of principled stand.   To get the credit for resigning on your principles you have to fooking well resign.  She was sacked.

Guy it was etiquette to say that even when you were forced out.  Basically all part of collective responsibility that you don’t question things even when being fired.
