BBC: The Queen will not attend Friday's Jubilee service at St Paul's Cathedral after experiencing discomfort while watching Thursday's parade at Buckingham Palace.
The decision was made with "great reluctance" after considering the "journey and activity required", the palace said.
However, she did take part in a beacon lighting ceremony on Thursday evening.
Four days of celebrations marking the Queen's 70-year reign began earlier.
The 96-year-old monarch appeared twice at Buckingham Palace balcony, flanked by other senior royals, as they watched a military parade and waved at thousands of well-wishers gathered on The Mall.
Hours after the ceremony, the palace confirmed she would not attend Friday's thanksgiving service, but said she "would like to thank all those who made today such a memorable occasion".
The service at St Paul's in central London will give thanks for the Queen's seven decades as monarch. » | Dulcie Lee & Hamzah Abbas, BBC News | Thursday, June 2, 2022
