Prince William, Kate support King Charles as he hosts Macron at Windsor despite red eye

The Royal Family on Tuesday shared pictures of King Charles and his family as they welcomed French President and his wife to Windsor Castle.

The pictures King Charles, Queen Camilla, Prince William and Kate Middleton with the guests were shared in both English and French languages that read, "The King and Queen, and The Prince and Princess of Wales, have welcomed President @EmmanuelMacron and Mrs. Macron to Windsor Castle."

King Charles welcomed French President Emmanuel Macron to Britain on Tuesday for the first state visit by a European leader since Brexit, their warm greeting symbolising the return of closer ties between the two countries.

Macron, treated to a British state visit for the first time, enjoys a strong personal relationship with the king, and there were smiles as the pair met alongside their wives, Brigitte and Queen Camilla, and watched over by soldiers on horseback, in ceremonial uniform of blue tunics and scarlet plumes.

In Windsor, accompanied by heir to the throne Prince William and his wife Princess Catherine, the group climbed into several horse-drawn carriages for a procession which finished in the medieval castle's courtyard, west of London.

The monarch's right eye was noticeably red when he met Macron. A Buckingham Palace source said he had suffered a burst blood vessel in one eye which was unrelated to any other health condition.
