Rolene Strauss of South Africa crowned her successor Mireia Lalaguna of Spain at the end of the event. It was the first time in the history of Miss World that Spain won the pageant.

Miss World is the oldest existing international beauty pageant. It was created in the United Kingdom by Eric Morley in 1951. Since his death in 2000, Morley's widow, Julia Morley, has co-chaired the pageant. Along with Miss Universe, Miss International, and Miss Earth, it is one of the Big Four beauty pageants.
