Queen Elizabeth II will miss the traditional royal garden party season, where she would normally meet with hundreds of people on the grounds of her residences in London and Edinburgh, palace officials said.
The 96-year-old monarch will be represented instead by other members of her family, Buckingham Palace said.
Before the pandemic, the Queen invited over 30,000 people each year to the gardens of Buckingham Palace or the Palace of Holyroodhouse in Edinburgh.
The guests, who have all served their community in different ways, have the opportunity to speak with the Queen and other royal family members at the parties.
The parties were set to return for the first time in three years starting next week.
