Remain, Labour and many in the media are running endless stories about the possible fall of the PM or the government. These stories are false mischief.
Let me remind you of the process to remove a Conservative PM. 15% of the Conservative MPs have to ask for a Confidence vote in the leader.Then more than half the MPs have to vote No Confidence. As most Conservative MPs support the Leader neither of these two events are about to happen.
For there to be an early General election the government would have to lose a Confidence motion in the Commons. I know of no Conservative. MP who would vote to do that. The DUP are not after an early election either.
