The Labour party has won a majority of seats in the 2024 UK General Elections, and Keir Starmer is expected to replace Rishi Sunak as Prime Minister. The Conservatives, in power for the last fourteen years, have suffered a rout, losing over two-thirds of their seats.
For me I’d say the one-nation part of the conservative party.
