I recently learned that in the UK, the Queen does not have a passport when she travels abroad, as the message in the passport states that the queen asks the bearer to pass through customs, so it would be redundant for the Queen to bear a passport. (source below)
In the US passport, the Secretary of State requests that the bearer be allowed to pass through. Given that in this situation, the Sec. State is analogous to the Queen and the passport would be redundant, does the Secretary of State (currently John Kerry) carry a passport when he travels abroad?
If anyone knows of other examples from around the world of people mentioned in passport messages who don’t use passports for a similar reason, I would be interested to know. (I’m not talking about refugees, world passport holders, etc. I’m interested in people in positions of power who don’t use passports)
