I suspect that King Charles is a converted Muslim. Remember, Christianity didn’t take over Europe through the masses, but through their rulers from the top down. Englishman should take King Charles and hang him.
Highly unlikely.
He's simply behaving as an imperial monarch (albeit one without an empire). A century and more ago, it was customary for British colonial rulers to occasionally ape the costumes of their subject peoples.
