Image source, ReutersPrince William is increasingly stepping up on the international stage. He greeted the French president today and they’ve met a number of times before.
Last month they were on stage together at an environmental event in Monaco about protecting the oceans. Prince William also saw Macron at the re-opening of the Notre Dame cathedral last year, where he had a meeting with President Trump, who is expected in the UK this autumn.
Catherine is back on duty, having spoken recently about the long lasting and “life changing” impact of chemotherapy, where she warned that getting back to normal was a slow process.
Let's go over to Windsor now as the town awaits the arrival of French President Macron and his wife Brigitte.
A stage is set in the town, with mounted household cavalry surrounding it. Band members are playing songs, including a rendition of Holding Out For a Hero.
Stick with us for the latest.

French President Macron is making his way to Windsor to meet the King and Queen Camilla before a carriage procession takes place through the town.
Close to a thousand people are now gathered outside Windsor Castle, which is decked with British and French flags on either side of the high street.
The mood by the barriers is chipper, with royal fans cheerfully chit-chatting to police officers lining the carriage procession route. Some are waving Union flags – and the occasional souvenir tea towel.
It’s very much a morning for the monarchists. French tricolours are few and far between in the crowd. The cross-Channel politics will come later in the state visit – for now, it’s all about the pageantry.
Image source, Getty ImagesMore now from Macron, who posted on social media moments after touching down in the UK.
"Together, we will address the major challenges of our time: security, defence, nuclear energy, space, innovation, artificial intelligence, migration, and culture," he says.
"The willingness expressed by the United Kingdom to strengthen ties with the European Union is a powerful signal — one that I welcome," Macron adds.
He also mentions efforts to support Ukraine, giving examples of the "vibrant and forward-looking" partnership.
"French and British: two free and proud peoples who never give up. That is what unites us, beyond any official texts. That is what binds us," he says.
French President Emmanuel Macron and his wife Brigitte are now on their way to Windsor, where they will be met by the King and Queen.

The Princess of Wales is mixing French and British for her outfit today.
Kate is expected to welcome the French president and his wife Brigitte at RAF Northolt alongside William, the Prince of Wales.
Catherine is wearing Christian Dior and a hat by British milliner, Jess Collett. The Christian Dior jacket is inspired by an original creation by the designer himself in 1947.

Image source, Getty ImagesState visits are a strange mix of pageantry and politics. In the case of the French visit, it’s a mix of horses and horse-trading.
There will be a ceremonial carriage procession, jangling along past the crowds, and a visit to see a horse given by President Macron to the late Queen Elizabeth.
But then there will also be negotiations between Prime Minister Keir Starmer and President Macron about stopping people crossing the English Channel on small boats and trying to firm up the coalition supporting Ukraine.
Among all of that, will be a series of glitzy photo opportunities, with the UK's French visitors being feted by the King and Queen as well as the Prince and Princess of Wales.
