Prince William will play a significant and special role in King Charles' Coronation and with only a matter of hours left for the event, he has revealed his wish for the big day.
The Prince and Princess of Wales visited Soho in central London yesterday and took time to chat with royal fans, tourists and Londoners.
They took photos and selfies with fans who gathered to see them - and while talking to the crowd, William said he is "praying for good weather " on Saturday.
A woman asked him: "William, how are you feeling about Saturday?"
And the Prince of Wales replied: "Good, good, thank you. If all goes well, good. Fingers crossed, good weather as well."
But his wish may not come true as the Met Office warned of a 60 per cent chance of light rain from 9am until midday tomorrow.
This will rise to an 80 to 90 per cent chance of heavy rain until 2pm, forecasters added.
Because of adverse weather, the flypast arranged for 2.30pm is also at risk of being cancelled or scaled down.
The RAF will assess the weather forecast until the last minute and only make a decision about cancelling the flypast one or two hours before it is due to take place.
According to reports, parts of the flypast or all of it could be moderated or cancelled outright due to the weather.
Because of the Coronation, flight restrictions will be imposed on light aircraft and drones above London on Friday and Saturday.
Transport Secretary Mark Harper also banned aircraft from flying below 2,500ft in an area including Buckingham Palace and Westminster Abbey from 9am tomorrow until 9pm on Saturday.
Commercial flights will not be affected, it is understood.
During their visit yesterday, William and Kate also took their first trip on the Elizabeth line, which was named after Queen Elizabeth II and is the latest line on London's train network.
They stopped at the historic Dog and Duck pub, where William went behind the bar and poured a pint of Kingmaker, a pale ale brewed to celebrate the coronation.
William joked that he would have to watch how much he drank and "get back into work mode".
Union Jack bunting and crown decorations have appeared across the capital, while Big Ben was lit up in red as part of late-night dress rehearsals around midnight on Wednesday.
Some 100 heads of state, representatives from 200 countries and hundreds of thousands of visitors are expected to descend on London for the historic event. Many die-hard royal fans are already camped out near Buckingham Palace to secure the best viewing spot.
"We've always been a massive fan of the Royal Family. I was also over for the (queen's) jubilee, so all the big moments that we can, we come over," said Luisa Rawes, from Portugal. "It is a massive occasion."
