Question to the Foreign, Commonwealth & Development Office:
To ask His Majesty's Government what consular support they offer to UK dual nationals resident in other states of which they also hold citizenship.
Where a dual British national is living or travelling in the country of their other nationality, we would not normally provide consular support or get involved in dealings between them and the authorities of that country. We may make an exception if we consider that the individual is vulnerable because of their specific circumstances, and there are special humanitarian or human rights reasons. The policy is set out here [https://www.gov.uk/guidance/who-the-fcdo-can-support-abroad%23dual-nationals].
