a new concept "monarchical republic".
Constantine of Greece has no status in a republic, because he must be integrated into the republic, as others.
In the case of Constantine he should:
a: Swear publicly a Republican constitution.
b: he must have a Greek surname
c: he must sign a document waiving any claim against the Greek state
In conclusion, He has that renounce to believe in a monarchical state.
Why has he that renounce to his belief if within a republic exist people that think
differently?, these people will take to sign the same document that constantine because they believe in other forms of State.
addition,he has family reasons for not taking a Greek surname.
I would not like that in the future, Prince Paul could not have surname "Greece" because his father renounced to it, and yet open a magazine and see the daughters of Prince Michael with the surname Greece and thereby justify a title that is not theirs.
