At the very least he lost his free lodging/staff (though it sounds like the royal family will pay for his new lodging somewhere else).

A large amount he's lost is also ceremonial, it sounds like he won't be removed from the line of succession cause that would require approval from all the separate countries the monarchy reigns over to do so (and he's like eighth in line so extremely unlikely given his age).

He's been excluded from a lot of official events already so a lot of it is just making it official.

He's still not being criminally charged with anything from the government.
