Just having a look at the parliamentary maths:
https://www.parliament.uk/mps-lords-and ... e-parties/.
Conservative + DUP have 321 seats
Sinn Féin and Speaker don't vote (excepting tie-breaks for Bercow)
Everyone else has 320 seats.
There's 1 vacant in Brecon where they fired their tory MP, and the Tories are standing him again. PC, Green, CHUK and Renew (who?) have all stood aside in favour of the Lib Dem candidate who leads polls by 15%. This by-election is due 1st of August.
As of lunchtime today, Boris will have a "workable" majority of 1 (assuming no immediate resignations); which will most likely be down to 0 by the time they get back from holiday.
Q1: How many Tory MPs will resign the whip within 24 hours of Boris being announced? So before recess and the chance to kick-start a GE straight away - there's time post-recess, but barely.
Q2: Are there any independents that Boris could negotiate with to support the government? most are ex-labour and ex-conservative, so I doubt it, but there may be 1-2 out there.
Q3: What happens if Boris can't commant a majority in parliament? Can he try his hand at minority governing (and can we imagine many worse candidates for doing so?) Or does he have to go to the queen and tell her that he can't build a government, and call a GE?
Q4: When Boris tries to deny reality and try a minority government - how long before someone else calls for a vote of no-confidence and force a GE?
Q5: How do potential Tory defections (whether to LibDem or independent, can't see CHUK getting any) change the maths? How about if they're big names.
Obviously, a GE doesn't solve anything, and will necessitate a grand-coalition of some description, probably involving 3 parties (Con + BnP + DUP could probably exist, albeit only in nightmares; but Lab + LibDem + SNP would slmost certainly require Corbyn's resignation)
