Prince Charles, Camilla Parker Bowles, Prince William, Kate Middleton, Prince Harry, and Meghan Markle’s royal engagements say a lot about their dedication to the royal family. But the number of times that they spent with each other also say something about their marriages.

According to Express, the Duke and Duchess of Cornwall are the most in-love couple because they were able to spend 24 percent of their time together while engaged in their royal duties. Prince Charles has undertaken 136 engagements so far this year, while Camilla has attended 69 engagements.

Out of these figures, Prince Charles and Camilla have undertaken 40 joint royal engagements together out of 165.

Prince William and Middleton, on the other hand, are the most united couple because they have spent 16 percent of their combined royal engagements with each other. As of late, the Duke of Cambridge has already completed 73 engagements, while Middleton has completed 46 engagements. The royal couple’s combined total number of engagements is at 103.

Markle and Prince Harry are the most besotted couple because they have spent the most time together while attending their royal engagements. The Duke of Sussex has completed 84 engagement thus far, while Markle has worked on 38 royal engagements this year.

Earlier this year, Markle went on four-month maternity leave after she welcomed her son, Archie. The royal couple has spent 27 percent of their engagements together.

Prince Edward and Sophie, Countess of Wessex have been dubbed as the most independent couple. Prince Edward has already completed 88 royal engagements, while Sophie has completed 62 royal engagements.

But despite their busy schedule, Prince Edward and Sophie have only attended four engagements together. This means that only three percent of their royal engagements were done together.

Meanwhile, an analysis from the Court Circular also revealed that Princess Anne is still the most hardworking member of the royal family this year. However, the number of engagements could still change in the coming months.
