Betting markets are placing long odds on ousting Prime Minister Boris Johnson.
Betting on him to remain prime minister is 1/10 with the odds of him losing the vote at 7/1.
A Reuters tally puts the number of MPs publicly supporting the prime minister at 164, of which 180 are needed. However, the vote is secret, so a public endorsement might not be worth much.
In any case, everything will be revealed at the top of the hour. Most notable to me is that Johnson promised MPs a tax cut at a meeting today. It is a promise that will have to be kept and which could add inflationary pressures on the pound sterling.
