The Queen will attend the annual Remembrance Day service at the Cenotaph, Buckingham Palace confirmed on Thursday, as Prince Charles said his mother was "doing alright".
The monarch, 95, has been resting on doctors' orders. She cancelled all public engagements after being advised to slow down following a night in hospital, when she underwent preliminary tests, last month.
Although she will appear on the balcony of the Foreign Office building to watch the annual wreath laying on Sunday, the Queen has decided not to attend the General Synod service and opening session next Tuesday. The Earl of Wessex will attend as planned, a royal aide said.
Buckingham Palace had previously said it was the monarch's "firm intention" to attend the Remembrance Sunday service, and her presence will be likely to assuage fears about her health.
Since her hospital stay, the Queen has been seen out driving on the Windsor estate and apparently in good spirits at Sandringham, where she enjoyed a private break last weekend.
Prince Charles was asked about his mother by a well-wisher in Brixton, south London. He gave the man a reassuring pat on the arm and said: "She's alright, thank you." The Prince had been meeting young entrepreneurs helped by his youth charity, the Prince's Trust.
On encountering performer Chris Wall, known as Chris Reads Minds, he initially appeared slightly nervous but entered into the spirit of his act.
The magician asked him to think of a name, number and colour. Charles quickly chose blue and the number 12 but struggled to think of a name. "Any name?" he asked. "Of any person? Oh dear…" He eventually then laughed and said the name of his eldest grandchild, George.
The magician went on to reveal one of his business cards, hidden in a sealed envelope in a wallet, on which the identical answers had been written. Prince Charles chuckled and said: "Very impressive – it really is."
Mr Wall, from Brockley, south London, was supported by the Prince's Trust as he sought to become a full-time magician when lost his job just before the start of the Covid pandemic. He said: "It was fantastic just to be able to thank the Prince in person."
