Watch: Prince Charles hails arrival of fifth grandchild Lilibet 'such happy news'
Prince Charles couldn't help but laugh as he was presented with the gift of Lycra for one of his grandchildren, days after welcoming his second granddaughter.
Charles, 72, was supporting the British Asian Trust's palace on wheels cycling event, which will see a group of fundraising cyclists travel 250miles over four days, via various royal residences.
Launching the cyclists from Highgrove, his Gloucester home, the Prince of Wales jumped on a bike for brief pedal himself, but did not don Lycra.
Jumping on the bike he warned: "I haven’t worked out the gears. I hope I don’t bump into you or get stuck behind you later on."
He admitted he had not cycled for years, but said he'd had a little practice last week.
When he was given a present of a small Lycra jersey, he descended into giggles as he stretched it, joking about it fitting him.
One of the cyclists, Rohit Chadda, joked: "Oh, have we got the wrong one?
"I think there is another one for you, but I've just been handed this one."
Charles said: "I mean, I have heard about Lycra, but really!"
Earlier, he had joked with the riders after seeing them in tight fitting riding gear that they were "a very good demonstration of why I don’t wear Lycra!"
"It’s a nightmare getting into it," he added.
The group will start at Highgrove, then travel through the Cotswolds towards Windsor Castle, onto London to Buckingham Palace, from the Tower of London to Cambridge with riders celebrating the end of the cycle at Sandringham on Sunday.
Prince Charles founded the British Asian Trust in 2007 with a number of British Asian business leaders, and has been supportive of their work in reducing poverty and disadvantage for communities in South Asia.
Although Charles's newest grandchild is Lilibet, who is not yet one week old, the cycling jersey appeared about the right size for Prince George, his oldest grandson.
Charles called the arrival of Lilibet Diana "happy news" in an engagement on Tuesday, his first since the announcement of his fifth grandchild.
Since then a dispute has arisen between the Duke and Duchess of Sussex and the palace, after sources told the BBC that they had not asked the Queen about using her childhood nickname as their daughter's name.
However the California-based couple hit back, saying they would not have named her Lilibet if the Queen had not been supportive.
The Royal Family are marking what would have been Prince Philip's 100th birthday, with Prince Edward and Princess Anne carrying out interviews in memory of their father.
The Queen presided over the planting of a rose in the East Terrace Garden of Windsor Castle. The newly-bred rose was named after the Duke of Edinburgh.
