King Charles III and Queen Camilla are taking their place on thrones.

At Westminster Hall in London, the new monarch was joined by wife Camilla, Queen Consort, as they met with 900 members of the legislative body and members of the House of Lords, who offered their condolences in the wake of Queen Elizabeth's death.

In his reply to the address, the King said he was "deeply grateful" for the outpouring of support and also pledged allegiance to the country's constitutional monarchy.

"While very young, her late Majesty pledged herself to serve her country and her people and to maintain the precious principles of constitutional government which lie at the heart of our nation," the new monarch said. "This vow, she kept with unsurpassed devotion. She set an example of selfless duty which with God's help and your counsels I am resolved faithfully to follow."

King Charles also appeared emotional as "God Save the King" was sung in his presence for the first time. Camilla, 75, also joined in the U.K.'s national anthem.

The King will now undertake a four-nation mourning tour, with Monday marking the next part of the Queen's journey to her final resting place in Windsor.
