Commonwealth citizen
For example, a woman who was a New Zealand citizen and married to a CUKC with right of abode on 31 December 1982, and who subsequently moves to the UK with her husband and naturalises as British citizen can claim the right of abode in the UK both through her British citizenship and through her status as a Commonwealth citizen who was married to a CUKC with right of abode on 31 December 1982. Therefore, if she were to renounce her British citizenship, she would still hold right of abode as a Commonwealth citizen married to a CUKC. However, if she were to renounce her New Zealand citizenship, she would permanently lose her ability to claim a right of abode through her Commonwealth citizenship and marriage to a British citizen on 31 December 1982, and would only be able to claim a right of abode through her British citizenship.
