In February 1991, the
Italian Communist Party (PCI) split into the
Democratic Party of the Left (PDS), led by
Achille Occhetto, and the
Communist Refoundation Party (PRC), headed by
Armando Cossutta. Occhetto, leader of the PCI since 1988, stunned the party faithfully assembled in a working-class section of Bologna with a speech heralding the end of Communism, a move now referred to in Italian politics as the
svolta della Bolognina (Bolognina turning point). The collapse of the
Communist governments in the Soviet Union and Eastern Europe had convinced Occhetto that the era of
Eurocommunism was over, and he transformed the PCI into a progressive left-wing party, the PDS. A third of the PCI's former members, led by Cossutta, refused to join the PDS, and founded the Communist Refoundation Party. The coalition ended in 1991 when the
Italian Republican Party (PRI) withdrew its support from the coalition over its failure to be given the Ministry of Communications. On 29 March 1991, the 5-party
Andreotti VI Cabinet was replaced with the 4-party (quadripartito)
Andreotti VII cabinet. On 17 February 1992, judge
Antonio Di Pietro had
Mario Chiesa, a member of the
Italian Socialist Party (PSI), arrested for accepting a bribe from a Milan cleaning firm. The Socialists distanced themselves from Chiesa.
Bettino Craxi called Chiesa
mariuolo, or "villain", a "wild splinter" of the otherwise clean PSI. Upset over this treatment by his former colleagues, Chiesa began to give information about corruption implicating his colleagues. This marked the beginning of the
Mani pulite investigation; news of political corruption began spreading in the press. In February 1991, the
Northern League, which was first launched as an upgrade of the Northern Alliance in December 1989, was officially transformed into a party through the merger of various regional parties, notably including Lombard League and Venetian League, under the leadership of
Umberto Bossi. These continue to exist as "national" sections of the federal party. The Northern League exploited resentment against
Rome's
centralism (with the famous slogan
Roma ladrona, which loosely means "Rome big thief") and the Italian government, common in northern Italy, as many northerners felt that the government wasted resources collected mostly from northerners' taxes. Cultural influences from bordering countries in the North and resentment against
illegal immigrants were also exploited. The party's electoral successes began roughly at a time when public disillusionment with the established political parties was at its height. The
Tangentopoli corruption scandals, which invested most of the established parties, were unveiled from 1992 on. it became the fourth largest party of the country and within the
Italian Parliament. ==Parties and leaders==
