To ask the Secretary of State for the Home Department what regulations govern the re-admission to the UK of a UK national who has taken US citizenship but whose citizenship has been revoked upon deportation from the United States. (312726)

[holding answer 25 January 2010]: All passengers, including deportees, who claim to be British nationals, must be able to demonstrate this on arrival in the UK. This is normally achieved by presentation of a valid travel document, confirming their nationality and identity. The requirement is irrespective of any other nationality currently or previously held by the passenger.

British nationals are not subject to immigration control; however, all arriving passengers are checked against the Watchlist. In certain circumstances, their arrival in the UK may be referred to other law enforcement agencies, for further action.
