The Queen’s Covid scare has reignited debate over which royals should be allowed to step up and fill in for her if she's unable to fulfil duties.
Yesterday, it was revealed that the monarch was being "monitored" after it emerged she had been in close contact with Prince Charles - just two days before he tested positive for Covid yesterday morning.
Buckingham Palace refused to confirm whether the 95-year-old monarch had tested positive or negative for Covid, fuelling fears for her health, but palace sources insisted she was not displaying symptoms of the virus.
