Miss World: My protest at 1970 beauty pageant
5 March 2014 Last updated at 00:42 GMT
In November 1970, a group of feminist activists stormed the stage at the Royal Albert Hall, to disrupt the Miss World Beauty contest.
Sally Alexander was one of those who organised the protest and talks about her motivations for disrupting the event, host Bob Hope's reaction and how it did not all go according to plan.
Witness is a World Service radio programme of the stories of our times told by the people who were there.
