It is a room filled with royals. Monarchs from all over the world gather at a reception hosted by Queen Elizabeth II.

At Windsor castle, Prince William and his wife Kate rub shoulders with King Abdullah of Jordan.

The gathering is part of the Diamond Jubilee celebrations and culminated with a group photo.

This year Britain marks 60 years since the Queen's accession to the throne in 1952.
