The event will take place at the British Normandy Memorial in Ver-sur-Mer, near Gold Beach in northern France, on June 6.

Charles will be accompanied by his wife and elder son, while Prince William will join Canadian veterans at the Juno Beach Center.

Prince William will represent his father, Prince Charles, at an international commemorative ceremony at Omaha Beach for the 77th anniversary of the D-Day landings.

The Prince of Wales and Camilla will then travel to France for a state visit, having attended the UK's national commemoration in Portsmouth on June 5.

Senior royals will participate in events in both countries, with many World War II veterans expected to attend.

Prince Charles, as head of state, is the commander-in-chief of the British armed forces and served in the Royal Navy and Royal Air Force.

His son, Prince William, was an RAF search and rescue pilot before transitioning to full-time royal duties.

Prince William's wife Catherine is absent from the commemorations due to her cancer treatment.

Her last public appearance was in December 2021.

Prince Charles, who was diagnosed with cancer in February, has resumed his official duties after doctors reported encouraging progress in his treatment.

This week, he attended a garden party at Buckingham Palace, a commemoration service at St. Paul's Cathedral, and unveiled a new official portrait of himself.
