Question to the Home Office:
To ask the Secretary of State for the Home Department, whether Irish citizens living in the UK with a parent born in the British dominion of Ireland before 1949 are eligible for automatic British citizenship.
An Irish citizen whose parent was born in Ireland prior to 1949 would be a British citizen at birth if they were born in the UK before 1983; or born in the UK thereafter at a time when their parent was ordinarily resident here.
If born outside of the UK after 1949, they would be a British citizen only where their parent retained an ongoing ability to pass on British nationality.
Where the circumstances above do not apply, they are able to seek naturalisation as a British citizen provided they meet the statutory requirements.
