Princess Michael of Kent is self-isolating in her Kensington Palace apartment after being diagnosed with coronavirus.
According to The Sun on Sunday, the 75-year-old royal has been unwell for almost a month, apparently suffering from the effects of long-Covid.
Princess Michael, and her husband Prince Michael, have both been in quarantine for three weeks.
Prince Michael, The Queen’s paternal cousin, tested negative for the illness.
A spokesperson for the couple said: “Princess Michael of Kent’s housekeeper fell ill three weeks ago and HRH was immediately tested and was found to be positive for Covid.
“She and her husband Prince Michael have remained in isolation at Kensington Palace ever since.”
The Sun reports that Princess Michael is suffering fro extreme fatigue and terrible fevers.
Princess Michael is the third member of The Royal Family to be known to have have been diagnosed with coronavirus.
In March, the Prince of Wales tested positive for the illness and spent a period of isolation in the Balmoral Estate along with the Duchess of Cornwall.
It was recently revealed that the Duke of Cambridge was also diagnosed with Covid at around the same time, although his positive test result was not made public at the time so not to alarm people.
Princess Michael of Kent lives with her husband at Kensington Palace, and from 2008 onward, pay their own rent on the five-bedroom apartment. The Queen previously granted them a grace-and-favour apartment, but when the cost of rent was made public, the outcry was too great and they began paying it themselves.
The Royal Couple receives no allowance from the Privy Purse, and do not usually carry out engagements on behalf of the Queen. They have however been called upon in the past to represent Her Majesty overseas, and they attend family events.
