King Charles and Queen Consort land in Belfast

STORY: Charles, 73, is travelling to the four parts of the United Kingdom before the queen's funeral on September 19.

Elizabeth died on Thursday (Sept. 8) in her holiday home at Balmoral Castle, in the Scottish Highlands, at the age of 96 after a 70-year reign, plunging the nation into mourning.

Charles, who automatically became king of the United Kingdom and 14 other realms including Australia, Canada and Jamaica, will be joined by new Prime Minister Liz Truss.

In Belfast, he will meet senior politicians and faith leaders and attend a service at the city's St Anne's Cathedral before returning to London.
