King Charles will invite foreign monarchs to his Coronation, breaking a longstanding tradition.

The guest list has been reduced from 8,000 to 2,000, but the King has expanded the type of guests.

King Charles wants to change the British monarch's Coronation, which traditionally excludes other crowned Royals.

European and Arab monarchs, including the King of Jordan and the Sultan of Oman, will be invited.

The change is intended to promote diplomacy and soft power.

Prince Albert of Monaco hinted at the change in January, but it has been kept secret until now.

It is uncertain whether Prince Harry and Meghan will attend from their home in California.

King Charles has reduced the "homage" portion and added charity representatives.

The Coronation is a solemn religious ceremony that has remained essentially the same for over a thousand years.
