The Prince of Wales, 71, has tested positive for coronavirus and is displaying mild symptoms “but otherwise remains in good health”, Clarence House has said.
A Clarence House spokesman said the Duchess of Cornwall, 72, had also been tested but does not have the virus.
In accordance with Government and medical advice, the Prince and the Duchess are now self-isolating at home in Scotland.
The tests were carried out by the NHS in Aberdeenshire where they met the criteria required for testing.
It is not possible to ascertain from whom the Prince caught the virus owing to the high number of engagements he carried out in his public role during recent weeks.
Charles’s last public engagement was on 12 March, but he did have a number of private meetings with Highgrove and Duchy individuals, all of whom have been made aware.
A small number of people living and working at Birkhall are remaining at the residence and self-isolating.
A source told PA that Charles had not seen the Queen since the morning of 12 March. Buckingham Palace said “the Queen remains in good health”.
