Original sentence: During his school years in the 1960s, Jospin joined the Internationalist Communist Organization, a secretive group dedicated to an unreconstructed Trotskyite program of overthrowing France's parliamentary democracy for the "dictatorship of the proletariat".Having lied hurt him politically more than having been in a cell of the revolutionary left, but the political damage was not severe or long-lasting in France, perhaps because of a public more cynically inured to scandal and more tolerant of Communism than in other Western countries such as the United States and United Kingdom.He remained active in it until the 1980s while also serving as a trusted member and high official of the Socialist Party.In 2001, investigative journalists and successive revelations by former Communist associates showed him to have been lying, and he confessed the truth.Jospin concealed this relationship, but specifically denied it when asked
