Rugby playing monarchs?

[Ticklishchap]

I was reading on another forum about the King of Tonga, Tāufa'āhau Tupou IV, being a very keen Rugby player in his youth. This has made me wonder about other Kings, Princes or other types of monarch in recent history who have been Rugby players. Any suggestions?

Does Prince Obolensky count?

Definitely.

I remember a friend of saying he'd played against a royal in a university match, based on dates and the fact he went to Exeter, I think it would have been Peter Phillips (son of Princess Anne).
