I don't see the need to get rid of her until Brexit.
Rather than remove a leader and become a new leader of a divided party that will be unable to deliver a deal that will unite the party, or parliament and get passed..... and hence result in your own post brexit resignation...
Let Theresa take the can for it.
With 40+ votes all EU agreements can be blocked.
This assures a WTO exit.
Which is fine by leaver MP's and fine by the electorate.
So, leaver MP's don't need to compromise or change anything to win.
The others if they recognise this relationship can get on with preparing for a no deal exit.
Lol. Fat chance. The others can keep remoaning ineffectually.
Can Mrs May change tack?
Is she sharp enough to say "I tried my best to get a deal. I offered them more than was reasonable to offer them and they still said 'no.'
No one can deny that the British government did it's best to get a deal with the EU. But we are unable to and so we are now walking away".
If she can bring herself to say that, she will align herself with the majority of the country and can keep office.
But she can't do it, because she's not feeling it. She is a remainer and she hasn't had the honour to resign.
