Colletti changed his political beliefs very often and abandoned many of his early Marxist ideals. Having been a member of the anti-fascist Action Party (Partito d'Azione; PdA) in his youth, he joined the Italian Communist Party (PCI) in 1949 and emerged as an important cultural party figure.[5] In 1964, Coletti left the PCI because the party's break with its semi-Stalinist past was leading towards what he called, in his view, a "patently rightward direction."[6] In the 1970s he was among the supporters of Socialist leader Bettino Craxi. From 1996 until his death he was elected on the list of Forza Italia, Silvio Berlusconi's right-wing political party, as a member of the Chamber of Deputies (lower house) in the Italian parliament.
