Worth noting that in the UK, much like in Spain, the main left party (Labour in this case) doesn't need to win a majority in order to form government while the main right (the Tories) do.
I think we can safely rule out any sort of Tory-SNP collaboration, this is not the 1970s anymore. Same with Tories-Plaid. And after the coalition and Brexit, even Tory-Lib Dem looks iffy though I guess not impossible. Maybe after Brexit it becomes more likely?
In any case for the Tories it is 326 or bust. They can depend on 8 or so DUP seats, Sinn Fein not taking their seats and maybe cooperation with the Lib Dems, but even that means they need to win upwards of 300 seats barring a Lib Dem surge in the future (and the Lib Dems being cooperative of course).
Meanwhile Labour doesn't need to come close anywhere near to a majority (or even to getting more seats than the Tories!) to form government.
They can fairly safely rely on the 45 or so seats of the SNP and another 5 seats or so from SDLP/Plaid/Greens. So that's +50 to whatever Labour gets. And of course the Lib Dem seats are a tossup.
So for a Labour government, whoever is the Labour leader can easily get into 10 Downing Street with only about somewhere around 270 seats, while the Tories would need at least 300 seats or more.
A result like this probably leads to a Labour government for example. Not a particularly stable Labour government but a Labour government nontheless
Con 295
Lab 270
SNP 45
Lib Dem 15
Plaid 3
Green 1
Speaker 1
Northern Ireland 18 (9 DUP, 6 SF, 2 SDLP, 1 Alliance)
For Labour: 321
For the Tories (generously giving them the Lib Dems, so if they go with Labour you can make the seat difference even larger!): 315
IDK though Brexit won ~63% of the seats with ~52% of the PV. Boris Johnson's coalition could be extremely efficient in seats per vote going forward.
I would think the way back for Labour starts with winning almost every 2016 Remain seat in England?
