Dual Nationality

Volume 492: debated on Tuesday 19 May 2009

To ask the Secretary of State for the Home Department how many citizens of the United Kingdom hold dual citizenship; and what the top 10 most common nations of dual citizenship are, ranked in descending order. (276485)

This information is not available. British citizenship can be acquired in a number of ways. For those who acquire that status automatically, by birth or descent, we do not have information about any other nationalities that they might also hold. For those who acquire British citizenship by registration or naturalisation, the UK Border Agency has records of the nationality that was held at the time of the application, but do not have figures as to how many retained another nationality on becoming British.
