If Tories have a clue they will talk in advance and agree who will be the next Tory Prime minister when May loses a confidence vote so they can select and elect him among themselves before the 14 day clock runs out that starts after a no confidence vote.
And also make sure the new Tory leader is acceptable for DUP since after no confidence vote failure the government needs to pass another confidence vote within 14 days.
However most likely May will be voted out inside Tories once 1 year has passed from the last Tory committee vote on the issue.
WTO-trade-Brexit will happen on 29th of March 2019 and open-borders-Merkel and elitist-Macron and Druncker- Juncker and cherry-Musk showed themselves to be hopelessly incompetent and totally miscalculating that UK would willingly subject themselves to years and years of new negotiations and uncertainty when May's shoddy and incompetent deal with EU having final say when and if UK can properly Brexit due to the backstop would have been passed.
WTO-trade-Brexit is good for UK markets and BAD for German markets and French markets.
