The Tories don't seem to have a clear frontrunner for the succession, it seems. They are prestty exhausted in terms of personenel, ideology and, well, competence, methinks.
Two group the Conservatives seem to be attractive for in terms of promotion prospects is immigrants, and women - I find that quite counterintuitive, but maybe Labour hates someone else besides Jews, too, and acts on it. Here are the names of some would-be candidates;
Rishi Sunak, apparently a bit of a front runner, the former Chancellor whose resignation ushered in the final days of BoJo. Maybe that will prove his undoing, because some Tories apparently don't want the honourable Brutus to replace the slain Caesar impersonator.
Sajid Savid, former Health Secretary and the
other Brutus; his and Sunak's resignation letters were published 9 min apart, for maximum destructive effect
Jeremy Hunt
Nadhim Zahawi. After BoJo, it might prove inconvenient to have an investigation for tax evasion on your heels.
Especially when you are the current Chancellor of the Exchequer (that's Finance Minister, you uneducated rednecks!)
Tom Tugendhat, a liberal and anti-Brexit Tory, some isolated specimens still exist, but count on a first round exit.
Suella Braverman
Kemi Badenoch
Penny Mordaunt
Liz Truss (Foreign Affairs) and Priti Patel (Interior), who has allegations of harassing of subordinates dragging on her, are expected to declare soon.
The count is exected to go up to a dirty dozen or more. You might see it as an
embarras de richesse, but I see it more as scraping the bottom of the barrel.
AFAIK, all the candidacies are collected by that ominous 1922 committee (made up of backbench MPs without government jobs) and put up for a vote among the Conservative MPs. They vote on the candidates and eliminate the weakest round after round. When the list has been reduced to two candidates, they put those two to the Tory membership, and whoever wins will be voted in as new PM by the MPs in turn - a rather exclusive intepretation of the term "representative democracy". Fresh general elections seem to not be on the menu, and the Tories know exactly why not.
