Brexit is saving her for now.
The trouble for the Tories who started plotting as soon as those exit polls came out is Brexit negotiations start in two weeks. The sight of a leader who has been toppled and yet is still attending would sink the tories wholesale. So anyone who had plans to run in the leadership contest has to hold their horses for now. I fully expect the talks to be pushed back.
Then you have people in her party who have always hated her, but for party unity and of course to keep hold of power kept quiet for the election. I mean if she pulled of that majority they would have been sonned and could never make a move on her, but with these results expect off the record briefings and story's planted in the right wing press the DUP situation is the icing on the cake.
After all the ranting from the right wing press about the Corbyn and the IRA this whole thing is darkly hilarious.
