Queen Elizabeth updates: State funeral ends 11 days of ceremonies

Britain's King Charles III and his wife Camilla, Queen Consort, traveled on Monday from London to Edinburgh, where they will walk behind his mother's coffin as it is transported in a procession through the Scottish capital.

Thousands of people have lined the streets since the coffin carrying the late Queen Elizabeth II began its final journey from Balmoral Castle in Scotland, where the 96-year-old monarch died last Thursday. On Monday, the coffin will be moved from the Palace of Holyroodhouse to St. Giles' Cathedral, with Charles and Camilla walking behind it along Edinburgh's Royal Mile.

A service to celebrate the late queen's life will take place Monday afternoon at St. Giles' Cathedral, where members of the public will be able to pay their respects and view the coffin for 24 hours before it is flown to London on Tuesday.

Charles and Camilla will also hold a vigil at St. Giles Cathedral on Monday evening.

King Charles III addressed the U.K. Houses of Parliament for the first time as sovereign on Monday morning.

Speakers from both Houses of Parliament addressed the new king at Westminster Hall in London. Charles, accompanied by his wife Camilla, Queen Consort, then gave a reply in front of some 1,200 people gathered inside.

"As I stand before you today, I cannot help but feel the weight of history which surrounds us and which reminds us of the vital parliamentary traditions to which members of both Houses dedicate yourselves, with such personal commitment for the betterment of us all," Charles said in a brief speech.

"We gather today in remembrance of the remarkable span of the queen's dedicated service to her nations and peoples. 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," he added. "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."

Prince Harry, Duke of Sussex, paid tribute to his grandmother on Monday in his first statement since her death, thanking the late queen for her "commitment to service," "sound advice" and "infectious smile."

"In celebrating the life of my grandmother, Her Majesty The Queen—and in mourning her loss—we are all reminded of the guiding compass she was to so many in her commitment to service and duty," Harry said. "She was globally admired and respected. Her unwavering grace and dignity remained true throughout her life and now her everlasting legacy. Let us echo the words she spoke after the passing of her husband, Prince Philip, words which can bring comfort to all of us now: 'Life, of course, consists of final partings as well as first meetings.'"

"Granny, while this final parting brings us great sadness, I am forever grateful for all of our first meetings -- from my earliest childhood memories with you, to meeting you for the first time as my Commander-in-Chief, to the first moment you met my darling wife and hugged your beloved great- grandchildren," he continued. "I cherish these times shared with you, and the many other special moments in between. You are already sorely missed, not just by us, but by the world over. And as it comes to first meetings, we now honour my father in his new role as King Charles III."

"Thank you for your commitment to service. Thank you for your sound advice. Thank you for your infectious smile," he added. "We, too, smile knowing that you and grandpa are reunited now, and both together in peace."
