@Mame,
Lots of big beasts will be losing their seats.
It's known as a Portillo moment, after cabinet minister Michael Portillo lost his "safe" seat in the 1997 election.
There is talk that Rishi Sunak's seat is in danger.
The only fly in the ointment is the possibility that Frogface Farage may be elected MP for Clacton.
This however is an election the Tories are losing. It's not one Labour are winning.
The anti Tory vote will give some surprises. The Greens are expected to gain a few seats, they currently have one.
Also pro Palestinian parties in Muslim majority seats may make an impact.
There's also Farage's far right Reform Party, but that is more likely to split the Tory vote than get many seats in their own right.
