The Royal Palace of Belgium announced that King Philippe and Queen Mathilde will attend the state funeral of British Queen Elizabeth II on Monday 19 September.
Following her death on Thursday, Buckingham Palace announced that the Queen's funeral will take place on 19 September, at 10:00 (GMT) at Westminster Abbey. Later, she will be buried in St. George's Chapel, next to her late husband Prince Philip.
State leaders from around the world are expected to attend the funeral, including US President Joe Biden, French President Emmanuel Macron, the European Commission president Ursula von der Leyen, as well as leaders of Commonwealth countries.
Belgium's King Philippe and Queen Mathilde will also be paying tribute to the late Queen, the Palace announced on Monday. Both will make the trip to London on 19 September for the funeral.
This is not the first time both countries' monarchs have attended each other's funerals; in 1993, Queen Elizabeth II broke royal protocol to attend King Baudoin's funeral. The reigning monarch in the UK usually sends a representative in their place, instead of attending the funeral themselves.
