According to the outlet, the pair are isolating at their country estate in Gatcombe Park in Gloucestershire.
Now, it appears that the couple will not be spending time with Queen Elizabeth on Christmas.
"Who will be with the Queen at Windsor on Christmas Day? Not Princess Anne or her husband Vice Admiral Sir Tim Laurence. He has tested positive for Covid and Anne is isolating. Charles and Camilla and the Cambridges have still not said where they will be on Christmas Day," reporter Richard Palmer wrote on Twitter.
Palmer predicted that Prince William and Kate Middleton will still be at Windsor with the matriarch. "Lots of people have speculated and that would be my first guess too but the Cambridges are still working out their plans in the light of the Queen’s decision to cancel her Christmas at Sandringham," he shared.
Earlier this week, it was revealed that the monarch would not be hosting for the holidays due to the recent surge in COVID-19 cases.
Phil Dampier, who writes a weekly column for The Royal Observer, told The Sun that senior royals will make sure that the Queen isn't alone.
"Obviously it's going to be much smaller and it's going to be similar to last year," he noted. "Except obviously, the one big difference is that Prince Philip is not going to be there. It wouldn't surprise me if Prince Charles and Camilla, Prince Andrew and possible Prince Edward and Sophie Wessex and maybe some others — a small hard core of people — join her for lunch. But I think it's more likely to be a dozen people rather than the 30 or so up at Sandringham."
"At Windsor you've probably got a tailor-made bubble of people who are regularly tested and who will be able to cope with a smaller number of people," he continued. "So they work shifts where there's a certain number of people on and a certain number of people off. I can't believe that she'll be on her own completely. So I'm sure that some members of the family will join her on the day."
