The British passport is the travel document issued by the United Kingdom to individuals holding any form of British nationality. It grants the bearer international passage in accordance with visa requirements and serves as proof of citizenship. It also facilitates access to consular assistance from British embassies around the world. Passports are issued using royal prerogative, which is exercised by Her Majesty's Government. British citizen passports have been issued in the UK by Her Majesty's Passport Office, a division of the Home Office, since 2006. All passports issued in the UK since 2006 have been biometric.
