Prince Harry and Meghan Markle reportedly became increasingly frustrated with significant delays in securing passports for their children, leading them to even consider a change of surname to resolve the issue.

According to The Guardian, Harry, 40, turned to his uncle, Charles Spencer, for advice about the possibility of using the Spencer family name amid the delay.

The Duke and Duchess of Sussex were said to be “exasperated” after waiting nearly six months for passports for their children, Prince Archie, 6, and Princess Lilibet, 4—far beyond the typical three-week processing time.

“There was clear reluctance to issue passports for the kids,” a source close to the Sussexes reportedly told the outlet.

A source also confirmed to People that the wait was unusually long.

Meanwhile, a legal insider told The Guardian that officials may have been intentionally stalling the process because the applications included the HRH (His/Her Royal Highness) titles for both children.

One source told The Guardian, “The King hadn’t wanted Archie and Lili to carry the titles, most of all the HRH, and the British passports, once created, would be the first and perhaps the only legal proof of their names.”

However, The Daily Telegraph reported that Buckingham Palace strongly denied any involvement by the King or his team in the delay.
