King Charles pays tribute to his late mother Elizabeth on the first anniversary of her death

She was the longest-serving monarch in UK history and she left behind an incredible legacy.

Her eldest son, Charles, was thrust into the position he had spent his whole life waiting for on that day as he became the sovereign leader.

However, it wasn't until May this year that his coronation officially took place and saw him ascend to the throne.

“In marking the first anniversary of her late Majesty’s death and my accession, we recall with great affection her long life, devoted service and all she meant to so many of us," the King said in a statement recorded at Balmoral Castle.

“I am deeply grateful, too, for the love and support that has been shown to my wife and myself during this year as we do our utmost to be of service to you all.”

He also released an unseen photograph of the late monarch that was taken at Buckingham Palace on 16 October 1968.

It shows Elizabeth II in full royal regalia with her crown and her Order of the Garter star.

While it's the first anniversary of Queen Elizabeth's death, it's also the first full year of King Charles' reign.

However, Professor Heather Jones, professor of modern history at University College London, told the outlet that the world's eyes are still waiting for other problems to be resolved.

"There are issues about the transparency of royal finances, when the public pay a lot of money into this institution," the professor said.

"It's a weak point at the moment.

"They also need to offer some kind of response to the questions that will keep coming up about the legacy of slavery."

It will no doubt be a sombre day in the United Kingdom as many take pause to reflect on a year without the late Queen Elizabeth.
