King Charles, Emmanuel Macron's Windsor meeting: Exclusive details released

King Charles, Queen Camilla, Prince William and Kate Middleton welcomed French President Emmanuel Macron to Britain on Tuesday for the first state visit by a European leader since Brexit.

Macron and King Charles, who enjoy a strong personal relationship, were all smiles as they walked together alongside their wives, Brigitte and Queen Camilla.

The Prince and Princess of Wales were the first to greet the Macrons upon their arrival in England.

The future king and Queen all traveled to Windsor, where the French President and his wife were formally welcomed by King Charles and Queen Camilla before taking a horse-drawn carriage ride to Windsor Castle for a military display and traditional inspection.

The royal family's official Instagram account shared new stunning photos from grand reception, stating: "The King and Queen, and The Prince and Princess of Wales, have welcomed President @EmmanuelMacron and Mrs. Macron to Windsor Castle."

King Charles and Emmanuel Macron traveled in the 1902 State Landau carriage during a precession at Windsor Castle. The monarch hosted the first state visit at Windsor Castle in 11 years as Buckingham Palace is all about logistics.

The 76-year-old monarch is expected to emphasise "the multitude of complex threats" both countries face in a speech he will deliver at a state dinner at Windsor Castle.

Macron posted on X (formerly Twitter) on his arrival that "there is so much we can build together".

The two have countries jointly announced that French nuclear energy utility EDF will invest £1.1 billion ($1.5 billion) in a project to build a nuclear power station in eastern England.
