An exchange on 24 May 1983 between Diana Gould, an English schoolteacher and former Women's Royal Naval Service meteorological officer, and British prime minister Margaret Thatcher was voted in 1999 as one of Britain's most memorable television spots. Appearing as a member of the public on BBC Nationwide's On the Spot live election special, Gould confronted Thatcher over the sinking of the Belgrano, an Argentine warship, during the 1982 Falklands War between the United Kingdom and Argentina.
