They were out of order to make comments, in common with all politicians who make comments about other politicians, whether in the UK or not - it happens every day, and sometimes it bites them on the bum depending on who they have slagged off. Just look at some of their X accounts for an eye opener.
I don’t personally think Badenough was out of order to ask the question, but I do think she was naive to think people wouldn’t join the dots on members of her own party doing the same thing, including her - she accused Suella Braverman of having a very public nervous breakdown for example when they spatted.
It is endemic I think, politicians have become more frank and open about their views about all manner of things, including other politicians. I don’t think the tide can be turned, although I wish it could.
