The King chose the Tudor Crown as opposed to the former St Edward's Crown as his symbol

Natural landscapes from all four UK nations will also feature inside the updated documents, including Ben Nevis, the Lake District, Three Cliffs Bay and the Giant's Causeway.


It is the first full redesign of British passports in five years, when they changed from burgundy to dark blue following the UK's departure from the European Union.


Passports featuring Queen Elizabeth II's coat of arms would remain valid until their expiry date, the government said.


Passports have been issued in the King's name since 2023, with their pages referring to "His Majesty", but the late Queen's coat of arms has remained on the cover.

As part of the transition from one reign to another, images and insignia of the King have gradually been introduced - including on stamps, coins and banknotes - with an effort to use up existing stocks rather than have an abrupt change.


By convention, the King himself does not have a passport because it is a document issued in his own name.
The latest visible change.

Almost all British institutions - Government, Police Forces, Royal Mail, Army, Royal Navy, Royal Air Force have updated already and other realms like Australia are pretty much along the same lines in terms of updates.
