Helen Elizabeth Morgan of the United Kingdom was crowned the winner at the end of the event by Mrs. Julia Morley, becoming the second Welsh and fourth woman from the United Kingdom to win the title. She resigned four days later on discovery that she had a child. Morgan was the first Miss World titleholder to officially resign, and the third not to finish her reign as Miss World, after Marjorie Wallace in 1973 and Lúcia Petterle in 1971.
Morgan had represented Wales in the 1974 Miss Universe pageant earlier that year and placed first runner-up to eventual winner Amparo Muñoz of Spain. When Muñoz relinquished her Miss Universe title later that year, Morgan had already been outed as a mother and, therefore, ineligible to succeed Muñoz as Miss Universe. Muñoz was not replaced by any of the other runner-ups.
