Prince Charles has the Coronavirus, and is displaying mild symptoms.
The heir to the throne is in isolation at Birkhall in Aberdeen, Scotland with his wife, Camilla, who has tested negative.
Their official residence, Clarence House, says it's 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".
Royal Commentator Dickie Arbiter speaks to Susie Ferguson.
