Prince Charles, Queen Elizabeth II's son and the first in line to the British throne, has tested positive for coronavirus and is now self-isolating in Scotland, said media reports.

Prince Charles, 71, is displaying mild symptoms "but otherwise remains in good health", a spokesman said, adding that Camilla Parker Bowles, the Duchess of Cornwall, 72, has been tested but does not have the virus.

Buckingham Palace has confirmed Queen Elizabeth II remains in good health, reported BBC.

The Queen, the palace added, "is following all the appropriate advice with regard to her welfare".

A Clarence House statement read: "In accordance with government and medical advice, the prince and the duchess are now self-isolating at home in Scotland.

According to BBC, the prince's last public engagement was on March 12, when he attended a Mansion House dinner hosted by William Russell, Lord Mayor of the City of London, and George Brandis, the High Commissioner for Australia, in aid of the Australian bushfire relief and recovery effort.

However, Charles has also been working from home over the last few days, and has held a number of private meetings with Highgrove and Duchy of Cornwall individuals, all of whom have been made aware, it added.
