Sarah Ferguson and Prince Andrew broke a number of protocols on their wedding day. But there was one thing that they deliberately did even after they were asked not to.

In the documentary “Finding Sarah: From Royalty to the Real World,” the Duchess of York told Oprah Winfrey that she and her husband were asked not to kiss on the balcony of Westminster Abbey. But knowing the royal couple, they both agreed to deliberately bend the rules.

The Duke and Duchess of York kissed on the balcony shortly after their wedding ceremony ended. This meant that they followed Prince Charles and Princess Diana’s iconic balcony kiss.

Ferguson didn’t explain why she and Prince Andrew were advised to not kiss in front of the public. But it is possible that the request had to do with Prince Andrew’s position in the line of succession.

Since Prince Charles and Princess Diana were the future King and Queen of England, they were given the special opportunity to kiss each other in public. But it is also important to note that it was Prince Andrew who encouraged the Prince and Princess of Wales to kiss.

In the book “Andrew: The Playboy Prince,” royal author Andrew Morton said that the Duke of York encouraged the newlyweds to share a kiss as a joke.

“On the palace balcony later, it was Andrew who was responsible for that kiss. As the bride and groom waved happily to the hundreds of thousands thronging outside the palace, Andrew urged Charles: ‘Go on, give her a kiss.’ Big brother obliged to the delight of the nation,” he said.

Prince Andrew also teased Prince Charles and Princess Diana on their wedding day when he told the late royal that she married his father. Prince Charles was much older than Princess Diana when they tied the knot. In fact, the couple had only been dating for a few months when they decided to get engaged.
