Happy birthday to the Prince of Wales! Prince Charles celebrated his 70th birthday on Wednesday evening, with a lavish party at Buckingham Palace. While the royal bash was a private affair, fans were able to catch a glimpse of the royals arriving at the Queen's London home in their chauffeur-driven cars. The birthday boy rode in the same car as his wife the Duchess of Cornwall, while the Queen waited at the palace to greet her son.

As the Prince and the Duchess zoomed past, photographers flashed their cameras, managing to sneak a peek of the couple. Charles looked dapper in a black tuxedo, while Camilla, 71, was lovely in a navy blue Bruce Oldfield gown.

Other royals who attended the glitzy bash included Charles' sons Prince William and Prince Harry, with their wives Kate and Meghan. The future King's siblings – Princess Anne, Prince Andrew and Prince Edward – were also among the guests. Meanwhile, members of European royal families also made an appearance, from Crown Princess Mary of Denmark to King Juan Carlos of Spain.

The Queen delivered a touching toast for her son Prince Charles, seen here posing with wife Camilla ahead of the birthday dinner. In front of guests, which included the royal family and members from royal families across Europe, the mother-of-four said: "It is a privilege for any mother to be able to propose a toast to her son on his 70th birthday. It means that you have lived long enough to see your child grow up. It is rather like —to use an analogy I am certain will find favour — planting a tree and being able to watch it grow."

She continued: "My mother saw me turn 70, of course. And she was heard to observe that 70 is exactly the age when the number of candles on your cake finally exceeds the amount of breath you have to blow them out. Over his 70 years, Philip and I have seen Charles become a champion of conservation and the arts, a great charitable leader — a dedicated and respected heir to the throne to stand comparison with any in history — and a wonderful father. Most of all, sustained by his wife Camilla, he is his own man, passionate and creative. So this toast is to wish a happy birthday to my son, in every respect a duchy original. To you Charles. To the Prince of Wales."
