British passports may be issued to people holding any of the various forms of British nationality, and may be used as evidence of the bearer's British nationality, and also, if applicable, evidence of the right of abode in the United Kingdom or evidence of citizenship of the European Union, or both. In 2015, British citizens had visa-free or visa-on-arrival access to 173 countries and territories, ranking the British citizen passport first in the world (tied with Germany).
