This thread seemed to be as good as any on which to post this ... so Tulip Siddiq has resigned.
She's not broken the ministerial code. She's not been
asked to resign by the PM. In fact, the standards advisor found no evidence that she'd done anything wrong.
However, she understood how things looked. She understood that staying in her position would mean that she would continue to generate stories (even if untrue). So, she (as have others) took the honourable route, and resigned.
If just one or two Tories had done this, then Johnson might not have had to quit, and they might even still be in power ... with him at the helm.
Funny old game, isn't it.
