The change likely holds special significance to King Charles.

One of the last constitutional duties his late mother performed before her death was appointing Truss as the new Prime Minister (this is a largely ceremonial duty as the position of PM traditionally goes to the leader of whichever party in Parliament gets the most seats in a general election).

And now, before his coronation, he’s already following suit.

King Charles will need to appoint a new Prime Minister as soon as posible. No details have been shared about who will take over for Truss, so be on the lookout for more information.

If you recall, Truss was sworn in as Prime Minister just two days before Queen Elizabeth tragically passed away at age 96.

During her reign, the queen welcomed a total of 15 Prime Ministers. While King Charles still has a long way to go, BBC journalist Philip Sim joked that King Charles is on track to make history (again).

“On current pace, King Charles could surpass his mother’s record of 15 prime ministers before the end of 2024,” he wrote on Twitter.

It’s the end of another era.
