The Palace spokesperson said: “Her Majesty The Queen remains in good health.
“The Queen last saw The Prince of Wales briefly after the investiture on the morning of 12th March and is following all the appropriate advice with regard to her welfare.”
Clarence House has said that the Prince of Wales is displaying mild symptoms of Covid-19 “but otherwise remains in good health”.
The 71-year-old is currently self-isolating at home in Scotland with his wife, the Duchess of Cornwall, who is 72.
A Clarence House spokesperson said that the Duchess has tested negative for the virus.
“In accordance with government and medical advice, the Prince and the Duchess are now self-isolating at home in Scotland,” they said.
“The tests were carried out by the NHS in Aberdeenshire where they met the criteria required for testing.”
The spokesperson added that it is “not possible to ascertain” when Prince Charles contracted the virus due to the “high number of engagements he carried out in his public role during recent weeks”.
A few days prior to their most recent meeting on Thursday 12 March, Prince Charles and the Queen both attended the Commonwealth Service at Westminster Abbey.
