To ask Her Majesty's Government what is their estimate of the number of British Nationals (Overseas) who qualify for British citizenship under section 4B of the British Nationality Act 1981. [HL1504]

It is difficult to provide an estimate number of British Nationals (Overseas) (BN(O)) who qualify for British Citizenship under Section 4B of the British Nationality Act 1981 as many of those with a claim to BN(O) status hold Chinese or another nationality and are thus not eligible. The number of those who only hold BN(O) status is not available, as we do not have access to figures of other countries' nationals.
