Camilla (Windsor?) is now Queen, not Queen Consort, whatever anyone thinks about that. My question: in the event that Charles predeceases his wife, William becomes King and Catherine becomes Queen. We would then have two queens, C & C. Is that allowed under our Royal constitution? Would Camilla be retitled, so to speak, or would Catherine have to wait until Camilla pegs it before she gets to be Queen? Any ideas?
