Queen Elizabeth II is sitting this one out.
To be specific, the Commonwealth Heads of Government meeting taking place later in the year.
According to the BBC, the announcement was made on Tuesday by Buckingham Palace, which said it was reviewing the number of long-haul trips Her Majesty takes.
The meeting is scheduled for November in Sri Lanka. The 87-year-old royal's son, Prince Charles, will represent his mother at the summit.
