How secure is Theresa May’s position as Prime Minister?

Calm leadership is today’s strong and stable. Theresa May has been trying to shrug off the plot against her, claiming her whole Cabinet is behind her. That may be true, but according to the former party chairman Grant Shapps, a couple might be carrying daggers. He claims around 30 Tory MPs so far want her out and it will grow. But his actions today have provoked a lot of fury too, with many laying into him in public and what’s supposed to be a private WhatsApp messaging group.
