Paris: King Charles III on Thursday pledged to do everything he could to strengthen the relationship between France and Britain, suggesting the “indispensable” partners should also team up to tackle the climate emergency.

In a speech at the French Senate on the second day of a three-day visit to France that London hopes will tighten post-Brexit relations, Charles won a standing ovation from lawmakers after deftly mixing English and French as well as personal and political reflections.

The visit has so far been seen in British and French media as a success, with occasional calls of “Vive le roi!” (“Long live the King!”) even heard on the streets of Paris.

In his speech, Charles recalled his mother Queen Elizabeth II, whom he succeeded upon her death one year ago, describing her legacy for France-UK relations as a “golden thread which will forever shine brightly” and saying the royal family was “moved beyond measure” by tributes to her from France.

“For the time that is granted to me as King, I pledge to do whatever I can to strengthen the indispensable relationship between the United Kingdom and France,” he said.

“Quite simply, the United Kingdom will always be one of France’s closest allies and best friends,” he said, speaking from a lectern adorned with British, French and EU flags.

‘Catastrophic destruction’

Charles suggested that France and Britain team up to tackle the climate and biodiversity emergencies with a new version of the Entente Cordiale, the 1904 pact that sealed the friendship between Paris and London.

“I would like to propose it also becomes an ‘Entente pour la Durabilite’ (Partnership for Sustainability) in order to tackle the global climate and biodiversity emergency more effectively,” he said.

He also vowed that London and Paris were “steadfast in our determination Ukraine will triumph” in fighting the Russian attack.

“Just as we stand together against military aggression, so must we strive together to protect the world from our most existential challenge of all - that of global warming, climate change and the catastrophic destruction of nature,” said the king, known for campaigning on environmental issues for the past decades.

By coincidence, Charles’s latest call on the environment came a day after Britain’s Prime Minister Rishi Sunak watered down green policies aimed at achieving net zero carbon emissions by mid-century.

His speech will also be etched in history as the first British monarch to speak in the main chamber of the Senate: his mother spoke in a conference hall within the Senate in a 2004 speech.

“Applause we can only dream of in our chambers!” said Senate speaker Gerard Larcher when lawmakers rose to their feet in unison after the speech as lower-house speaker Yael Braun-Pivet laughed in agreement.

Notre-Dame homage

The Senate speech is the diplomatic high point of the day that followed Wednesday’s banquet at the Versailles Palace hosted by President Emmanuel Macron.

Charles then visited the northern Paris suburb of Saint-Denis - home to the French national stadium used for the current Rugby World Cup and the Olympics next year - meeting residents and visiting its majestic mediaeval basilica.

He also rejoined Queen Camilla and French first lady Brigitte Macron - who even briefly played ping-pong while visiting a sports centre.

Later on the Ile de la Cite on the river Seine, Charles - a keen gardener who once admitted he talked to his plants - toured a flower market named after Queen Elizabeth II on her last state visit in 2014.

He and Camilla then greeted a crowd of well-wishers while walking to the nearby Notre-Dame Cathedral, which was partially destroyed by a devastating fire in 2019.

Joined again by the Macrons, they were shown the renovation and reconstruction work at the church, visiting in particular a gargoyle workshop.

Charles had said in an emotional message to Macron after the fire that he was “utterly heartbroken”, calling Notre-Dame “one of the greatest architectural achievements of Western civilisation”.

The king was to later attend a climate and biodiversity financing conference at the Natural History Museum, before wrapping up the Paris leg of the visit with a formal farewell from Macron at the Elysee Palace.

His final day will be spent in the southwestern city of Bordeaux.

The French president is known to have a strong personal rapport with Charles, with both men known for their love of books.

Commentators in France excitedly noted how Macron repeatedly touched Charles’s shoulder and his wife kissed Camilla, in a new protocol unthinkable under the more distant and austere Elizabeth II.
