Question to the Home Office:

To ask Her Majesty's Government whether they collect details of any other passports held by applicants for British passports; and whether this information is retained and available to Border Force immigration officers.

Dual national passport information provided as part of a British passport application is not routinely recorded as part of the assessment. Dual national information is not held centrally but Border Force may in some circumstances request passport information to support individual case assessments which may include any information recorded on dual nationality.
