this was extended under the immigration, asylum and nationality act 2006; people with dual nationality who are british nationals can be deprived of their british citizenship if the secretary of state is satisfied that "deprivation is conducive to the public good", or if nationality was obtained by means of fraud, false representation or concealment of a material fact. there is a right of appeal. this provision has been in force since 16 june 2006 when the immigration, nationality and asylum act 2006 (commencement no 1) order 2006 came into force. loss of british nationality in this way applies also to dual nationals who are british by birth. the secretary of state may not deprive a person of british nationality, unless obtained by means of fraud, false representation or concealment of a material fact, if they are satisfied that the order would make a person stateless. this provision was modified by the immigration act 2014 so as not to require that a third country would actually grant nationality to a person; british nationality can be revoked if "the secretary of state has reasonable grounds for believing that the person is able, under the law of a country or territory outside the united kingdom, to become a national of such a country or territory."
