The Queen will not attend a Commonwealth service at Westminster Abbey on Monday and will instead be represented by Prince Charles, Buckingham Palace has said.
In a statement, the palace said she had made the decision after discussing the arrangements with the Royal Household.
It would have been her first major engagement since having COVID-19 in February.
The Prince of Wales was already scheduled to attend the service, along with Camilla, Duchess of Cornwall, the Duke and Duchess of Cambridge and Princess Alexandra.
The palace has not given a specific reason why the Queen will not be there.
According to Sky News’ royal correspondent Rhiannon Mills, the decision to pull out of the event relates to “discussions that had been had about her comfort travelling to and attending the service.
“But the decision is not related to any illness,” Mills wrote on Twitter.

I understand the decision relates to discussions that had been had about her comfort travelling to and attending the service. But the decision is not related to any illness.
