@MarieDeGournay is there a way of asking a politician a question that they have to give a direct answer to?
If they don't want to answer, they will ignore / deflect / waffle. They've even been known to walk out of interviews.
They will also ignore / deflect / waffle if asked in writing.
I know Angela Rayner makes much of her no-nonsense, tell-it-like-it-is persona, but if she really doesn't want to answer, she won't.
