The official royal event calendar has resumed.

On Thursday morning, Prince Charles and Duchess Camilla hosted Emmanuel Macron at Clarence House in London. It was their first major government engagement following a return to London after months in lockdown at Birkhall.

The French president was visiting on the 80th anniversary of Charles de Gaulle's "Appel du 18 Juin" — his June 18, 1940, speech made from London to the French people on resistance against the country's Nazi occupiers during the Second World War.

The U.K. and French national anthems were played following the president's arrival. After that, he was invited to inspect a Guard of Honour alongside Prince Charles. 

A wreath-laying ceremony was conducted at Clarence House and Carlton Gardens to honour the U.K. and French leaders during the WWII years.

Wreaths were laid at a statue of Charles de Gaulle and at the King George VI and Queen Elizabeth Memorial. A minute of silence was observed following the laying of wreaths.

Afterward, President Macron spoke about the important day in French history. London was also presented with a Légion d’Honneur for its service to de Gaulle while he was exiled in London during WWII.

Clarence House shared an account of the event on its official Instagram page as well. Per the post, Prince Charles spoke on receiving the Légion d'Honneur:

"It gives me the utmost pleasure and pride to accept the Légion d’honneur on behalf of this city and this country, and on behalf of all those who struggled for liberty in common cause with France," Charles said.
