HELLO! understands that Prince Philip, who is said to be in "good spirits", walked into hospital by himself after travelling by car and that it was not an emergency admission. The stay in hospital is purely precautionary and the illness is not COVID-19 related.
The Queen has remained at Windsor Castle where she and her husband have been spending lockdown. On Thursday, she carried out her first official in-person event of the year, making one of her most senior royal aides, Vice-Admiral Sir Tony Johnstone-Burt, a Knight Commander of the Royal Victorian Order (RVO).
