King Charles seeks new Franco-British entente for sustainability

King Charles has said that Britain and France had a shared responsibility to protect democracy in Europe and to ensure the world tackles climate change, in what he called an "entente for sustainability".

Charles arrived in Paris on Wednesday for a three-day state visit, in a show of pageantry and symbolism meant to turn the page on years of rocky relations between the two nations since Britain voted to leave the European Union.

"Together, our potential is limitless," Charles said in flawless French, giving the first speech by a British monarch to representatives of both houses of the French parliament on Thursday.

"That's why we must cherish and take care of our Entente Cordiale. For future generations, so it becomes an entente for sustainability to tackle more efficiently the global urgency in terms of climate and diversity," he said.

The so-called Entente Cordiale was an alliance dating from 1904 that put a stop to centuries of military rivalries between France and Britain to see the two European powers fight on the same side during two world wars.

Symbolic gestures

With Russia's "unjustified aggression" in invading Ukraine 18 months ago, the two countries were once again facing war on the continent, he said.

"Together, we are unshakable in our determination that Ukraine will prevail," Charles said.

The warm words, visits and symbolic gestures come after several tense years over the negotiation of Britain's exit in 2020 from the European Union, and after that, rows over issues ranging from immigration to the sale of submarines.

Former British prime minister Liz Truss once said the jury was out on whether France was a friend or foe, before settling on calling it a friend last year. Her successor, Prime Minister Rishi Sunak, visited France in March to kick off what he called an "entente renewed".

"We must reinvigorate our friendship so that it is up to the challenges of the 21st century," Charles said in a toast at a state banquet held at the Palace of Versailles the day before.

The king is keen to walk in his mother's footsteps and has referred to Elizabeth's deep affection for France.

Charles, together with his wife Queen Camilla, French President Emmanuel Macron and his wife Brigitte, also visited Notre Dame Cathedral in Paris to view restoration works following a massive blaze in 2019 that destroyed its roof.

Macron and Charles have shared correspondence and insight on the restoration of the cathedral.

There were light moments too on the second day of the state visit, with Camilla and Brigitte Macron trying their hand at table tennis - not very successfully - as French youngsters looked on.

And Charles received a jersey from French soccer team Paris Saint-Germain, bearing his name and the number three, in a nod to his title King Charles III.
