"The Queen has reluctantly accepted medical advice to rest for the next few days," a spokesman for Buckingham Palace said in a statement on Wednesday. "Her Majesty is in good spirits and is disappointed that she will no longer be able to visit Northern Ireland, where she had been due to undertake a series of engagements today and tomorrow."
The queen gave her "warmest good wishes" to the people of Northern Ireland and expressed a desire to visit in the future.
A source told ET at the time that the decision to rest is not COVID-related, though the queen's condition is not currently being shared.
"She has had a packed schedule recently," the source says. "She is resting at Windsor Castle on doctors' advice."
