Meghan & Harry Were Sitting behind William & Kate at Their Final Royal Event Due to Royal Rules

Prince Harry and Meghan Markle sat behind Prince William and Kate Middleton during their final royal engagement on Monday, and royal watchers showed their concern.

On Monday, March 9, Prince Harry and Meghan Markle reunited with the former's brother, Prince William, and his wife, Kate Middleton, for the Commonwealth Day service at Westminster Abbey.

With the Commonwealth Day service behind them, the Sussexes were done with their senior royal duties.

While at the ceremony, the Duke and Duchess of Sussex sat behind William and Kate.

According to E! Online, the seating arrangement had caught the eyes of many royal observers who thought that it was an attempt to snub a party.

As it turned out, that wasn't the case as they had sat down that way in respect to the palace rules.

Succinctly put, the couples had sat down according to their ranks within the Firm as William is third in line to the throne while Harry is now sixth after his brother welcomed his children – Prince George, Princess Charlotte, and Prince Louis.

The rules had come into play after James II fled the country in 1688, as the royal website explained. Following that incident, Parliament believed that James had abandoned the government, thus making the throne unfilled.

The throne got subsequently offered to James's daughter Mary and her husband William of Orange as joint rulers, instead of his son.

With that in mind, Cosmopolitan revealed that the next person in line for the throne was the Prince of Wales, Prince Charles.

The 71-year-old, who is Queen Elizabeth II's firstborn son, used to be married to the late Princess Diana and is now married to Camilla Parker Bowles.

Meanwhile, the site also noted that with the Commonwealth Day service behind them, the Sussexes were done with their senior royal duties.

For the occasion, Meghan had rocked a gorgeous cape dress that caught the attention of observers.

The former "Suits" star paired the Emilia Wickstead dress with a matching fascinator, a Gabriella Hearst, and a pair of nude Aquazzura pumps.

Although Harry chose the same shade of green to match with his wife, the color was only noticeable when a gust of wind blew against his suit jacket to show off the lining beneath.
