The UK Conservatives keeps having "almost-Portillo" moments. Not as exciting as an actual loss, but point to an underlying vulnerability next time their not in the lead.
In 2017, the Home Secretary Amber Rudd came within 400 votes of losing her previously comfortable seat, and in 2019, then-Foreign Secretary Dominic Raab had his majority slashed to 1,000 votes.
If Labour win, become the largest party in 2024, the weirdness of the UK political map means that we're almost assured a new Portillo moment.
After the Lib Dems and SNP both lost their leaders in Westminster, and Labour lost their Shadow Chancellor and Shadow Foreign Secretary in 2015 , and a bunch of Shad-Cab members in 2019, it seems like the Tories are due a turn. (Also worth noting that Labour stalwarts like Yvette Cooper and Jon Tricket came within a hair's-breadth of their own Portillo moment in 2019. It can't be understaded just how devastating that election was for them. There's a reason it utterly destroyed what was left of the Corbyn project).
I would be extremely surprised if Raab kept his seat at the next election. So that’s one we can probably expect to add already to the board for the Tories.
