Queen Elizabeth II died aged 96 on 8 September, surrounded by the love of her family, at her summer residence Balmoral in Scotland.
On the eve of the funeral, King Charles expressed his gratitude as the world prepared to say a “last farewell” to the Queen, who he had described as a “cherished sovereign and a much-loved mother” in a heart-felt tribute soon after her death.
The King revealed that both he and Queen Consort Camilla have been "so deeply touched" and "moved beyond measure" by the condolences they’ve received since the Queen’s passing.
"I wanted simply to take this opportunity to say thank you to all those countless people who have been such a support and comfort to my family and myself in this time of grief," he said.
