She can't be got rid as leader of the Conservative party, so the only way she can go is if some Conservative MPs cute against a motion of no confidence. They isn't likely to happen.
Until May's speech blaming MPs for the delay the other day that is. Several Tory MPs are now saying they'd vote against her at a governmental vote of no-confidence. Added to that, she's lost the support of the whips office, so there's nobody going to be telling MPs they have to vote as she instructs. It's now a clear case of when she leaves rather than if, her leadership is over, only the job title remains until she comes to that realisation herself.
As for Corbyn, he was over in Brussels talking to a few leaders yesterday. Why he hasn't called for another no confidence vote yet, even though he would almost certainly win it at this stage, is unbelievable. Worst PM of all time coupled with worst opposition of all time, no wonder we're in such a mess!
