People in the U.K. are taking to the streets to celebrate the queen’s Platinum Jubilee, marking 70 years on the throne.

Thousands of street parties are being held over the four-day holiday weekend.

Prince Charles and his wife Camilla, Duchess of Cornwall took to Twitter to thank the public for their celebrations. “We have been touched to see so many people lining the streets," they wrote.

People around the world can also join in the celebration by trying recipes beloved by the royal family.

A 7-layer lemon Swiss roll and amaretti trifle that won the jubilee’s Platinum Pudding Competition is the perfect way to celebrate Elizabeth’s 70 years on the throne.

The pudding, or dessert, was made by amateur baker Jemma Melvin, 31, of Southport, and beat out over 5,000 entries.

If you prefer to celebrate with a tea party fit for a queen, Carolyn Robb, a former chef for the royal family, shared recipes with “Good Morning America” from her book, “Tea at the Palace.”

And if you would like to try scones specifically made for the queen, try this recipe for royal fruit scones made by Mark Flanagan, the personal chef to the queen and the head chef of the royal household.

Princess Anne stepped in for her mother, Elizabeth, Saturday at the Epsom Derby, a horse race in Surrey, England.

Anne, the only daughter of the queen and her late husband, Prince Philip, was spotted waving to crowds and speaking with officials at Epsom Downs.

Elizabeth was scheduled to attend the race as part of her Platinum Jubilee celebrations but Buckingham Palace confirmed Friday she would not attend. The 96-year-old queen, whose love for horses is well known, is expected to watch the race on television at Windsor Castle, according to the palace.

Jockeys at this year’s race honored the queen by wearing her official racing silks, according to a tweet from the Epsom Downs Twitter account.

Prince Harry and Meghan, Duchess of Sussex, are not expected to appear at any Platinum Jubilee events Saturday as they mark their daughter's first birthday.

A spokesperson for the couple said they “are planning to spend Saturday together privately as a family.”

The couple’s daughter, Lilibet "Lili" Diana Mountbatten-Windsor, turns 1 on Saturday, a birthday she is celebrating in the U.K., as both she and her brother, Archie, 3, traveled with their parents to celebrate Queen Elizabeth II’s Platinum Jubilee.

The trip is believed to be Lili’s first visit to the U.K. and the first opportunity for her to meet her namesake, Elizabeth, whose family nickname is Lilibet.

Harry and Meghan have so far made one public appearance at the jubilee, joining royal family members Friday at a National Service of Thanksgiving for the queen at St. Paul’s Cathedral in London.

The Sussexes have for the past two years lived in California, where Lili was born. She is the first senior royal baby born in the U.S. and the first great-grandchild of the queen to be born outside of the U.K.

Prince George and Princess Charlotte on Saturday made their second appearance at Queen Elizabeth II’s Platinum Jubilee celebrations.

George, 8, and Charlotte, 7, joined their parents, Prince William and Kate, Duchess of Cambridge, at Cardiff Castle, where they met performers and crew who will be taking part in Saturday night’s Platinum Jubilee Celebration Concert at the castle.

George, dressed in a blazer like his dad, and Charlotte, wearing a button-down coat like her mom, were seen waving to the crowds gathered and shaking hands with performers as they toured the concert preparations.

Absent from the visit was George and Charlotte’s younger brother, 4-year-old Louis, who joined them earlier this week at Trooping the Color. Louis made headlines at Trooping the Color for his hilarious facial expressions and his apparently close relationship with the queen.

The pair were seen talking and pointing to things on the balcony of Buckingham Palace as they watched the military flypast.

Queen Elizabeth II shared a written thank you message on Sunday to mark the end of four days of celebrations for her Platinum Jubilee.

"When it comes to how to mark seventy years as your Queen, there is no guidebook to follow. It really is a first. But I have been humbled and deeply touched that so many people have taken to the streets to celebrate my Platinum Jubilee," Elizabeth wrote. "While I may not have attended every event in person, my heart has been with you all; and I remain committed to serving you to the best of my ability, supported by my family."

"I have been inspired by the kindness, joy and kinship that has been so evident in recent days, and I hope this renewed sense of togetherness will be felt for many years to come," the queen continued. "I thank you most sincerely for your good wishes and for the part you have all played in these happy celebrations."

The queen signed her message with her first name, Elizabeth, followed by the letter R, which stands for Regina, the Latin word for queen.
