Theresa May and Brexit: Has the Tory party run out of patience? - BBC News
With both sides of her party angry over an offer to extend the Brexit transition, the prime minister faces a fight to survive.
It has become something of a weekend ritual that hardline Brexiteers breathe fire and brimstone and declare they are on the verge of triggering a vote of confidence in Theresa May.

On Monday mornings the chairman of the 1922 committee Sir Graham Brady inspects his office safe and finds a pile of letters in the corner falls short of the magic number - 48 - needed to trigger a vote.

And so the prime minister limps on for another week until the ritual starts out all over again.

This time, however, there is a different feel. Theresa May managed to achieve the extraordinary feat last week of uniting Remain and Leave Tories in despair after she floated the idea of extending the transition period after the UK leaves the EU. There are now Remain Tories saying the time has come for her to go.

Until now three factors have ensured that the prime minister has been safe from the sniping. If any of these change then the weekend ritual may have a different ending when Sir Graham opens his safe in the coming weeks.

For the moment these three factors are likely to mean that Theresa May will hang on. But the mood is changing. If you examine the three factors in reverse you can see how events could move against the prime minister:

The odds are that Theresa May will soldier on for the moment. She did after all exceed expectations in her recent Conservative party conference speech.

But Margaret Thatcher was cheered at the end of her speech to the 1990 conference. The following month she was out.
