• Prince William will not need a passport to travel abroad when he becomes king
  • Prince William and Kate Middleton have a skillful teamwork with Prince Charles and Camilla
  • The royals have an unwritten travel protocol that Prince William and Kate Middleton already broke

Prince William will no longer be asked to present a passport when he travels abroad once he becomes king, unlike his wife, Kate Middleton.

The Duke of Cambridge is the second in line to the throne. He is expected to lead the monarchy after his father, Prince Charles.

Prince William and Middleton often travel abroad as part of their roles in the monarchy. The husband and wife are full-time working royals and often do official visits in other countries. Last year, they visited Pakistan.

When Prince William will be crowned king, traveling will be a bit different for him. The royal father of three will no longer need a passport. This rule applies to the current monarch, Queen Elizabeth II, and it was made because passports are issued in the name of the monarch.

“Her Britannic Majesty's Secretary of State requests and requires in the name of Her Majesty all those whom it may concern to allow the bearer to pass freely without let or hindrance and to afford the bearer such assistance and protection as may be necessary,” the note in the official document reads.

Queen Elizabeth II is the only person in the U.K. who doesn’t need a passport to travel. Prince Charles will also not need one when he takes over the throne.

Although the monarch doesn’t need a passport, there will always be an identity check. At present, Queen Elizabeth II has to answer a few questions to verify her identity. This process will also apply to Prince Charles and Prince William.

Meanwhile, the royals have unwritten rules when it comes to traveling. Prince William and Prince George are not allowed to travel in the same plane to avoid affecting the line of succession in case of a fatal accident.

However, Prince William and Middleton have broken the rule when they took Prince George to their Australia and New Zealand trips. An insider said that the future king actually asked Her Majesty’s permission and she agreed.

In related news, the Duke and Duchess of Cambridge have a “skillful teamwork” with the Prince of Wales and Duchess of Cornwall, according to royal commentator Richard Fitzwilliams. The expert said that the younger royals have been careful to not overshadow the heir apparent unlike Prince Harry and Meghan Markle.
