Since the years of high school, Cuperlo has been involved in politics as he joined the FGCI, the leader of which he became in 1988.
On 8 October 1990 the Fgci's secretary Gianni Cuperlo, proposed to Ariccia, following the line of Achille Occhetto, that the FGCI be dissolved in order to create the Sinistra Giovanile, a federal organisation with the aim of creating four associations in schools, in territories, in universities, in workplaces, all federated together.
