Before 1999, the winner of Miss Northern Ireland would have to compete in the Miss United Kingdom competition and win it in order to be applicable to compete in the Miss World competition. Since then however, the winner of each nation of the UK sends separate representatives to the Miss World pageant, the highest ranking of the four delegates is then named Miss United Kingdom, and competes at the Miss International Pageant the following year under the "Britain" or "United Kingdom" banner.
