So
Dominic Raab has ruled himself out of the Leadership Contest (This is perhaps significant with regards to Johnson. However Raab's problem is his wafer thin majority and the fact he is at risk of losing his seat at a General Election).
Other significant names who have ruled themselves out so far (and there maybe are some surprises here).
Matt Hancock, Michael Gove and Andrea Leadsom
So far three have made an official announcement of their intention to stand. Thats Suella Braverman, (she has 2 of the 8 noms she needs to be a candidate - Sir Desmond Swayne and Jason McCartney) Jake Berry and Steve Baker
There are two other candidates who is a seeming definite as they have allies publically go on record as nominating them. Thats Tom Tugendhat with 4. (Damian Green, John Stevenson, Aaron Bell and Robert Largan) and Liz Truss with 1 (Alec Shelbrooke)
Then those who are likely to stand but there is no official word from them or close associates are so far rumoured to be: Jeremy Hunt, Penny Mordaunt, Ben Wallace, Nadhim Zadhawi, Sajid Javid, Tobias Ellwood, Grant Shapps (Sky seem to have an inside track on him) and Rishi Sunak.
I suspect all are waiting to see the fog start to clear with regards to the ongoing squatter at No10 until they will be more willing to show their hands. Plus they will probably want to secure their 8 noms before making an embarassing statement and not being able to get into even the first round of votes.
I wouldn't rule out another wildcat option or two of Tory MPs chancing their luck - if only to try and get a promotion and Cabinet Role. There is bound to be another delussional candidate like Braverman...
