much-needed "structural reforms" that would modernize the country and create a modern social-democracy. In 1960, an attempt by the right wing of the Christian Democrats to incorporate the neo-fascist Italian Social Movement (MSI) in the Tambroni government led to violent and bloody riots (Genoa, Reggio Emilia), and was defeated. Up until the Nineties, two types of governmental coalitions characterised the politics of post-war Italy. The first were "centrist" coalitions led by the Christian Democracy party together with smaller parties: the PSDI, the PRT, and the PLI. The first democratic government (1947) excluded both the PCI and the PSI, which brought about the political period known as "centrist government", which ruled over Italian politics from 1948 to 1963. The centre-left coalition (DC-PRI-PSDI-PSI) was the second type of coalition that characterised Italian politics, coming about in 1963 when the PSI (formerly the opposition party) went into government with the DC. This coalition lasted in parliament first for 12 years (from 1964 to 1976) and then with a revival in the Eighties that lasted until the start of the Nineties. The PSI entered government in 1963. During the first year of the new Centre-Left Government, a wide range of measures were carried out which went some way towards the Socialist Party's requirements for governing in coalition with the Christian Democrats. These included taxation of real estate profits and of share dividends (designed to curb speculation), increases in pensions for various categories of workers, a law on school organisation (to provide for a unified secondary school with compulsory attendance up to the age of 14), the nationalisation of the electric-power industry, and significant wage rises for workers (including those in the newly nationalised electric-power industry), which led to a rise in consumer demand. Urged on by the PSI, the government also made brave attempts to tackle issues relating to welfare services, hospitals, the agrarian structure, urban development, education, and overall planning. For instance, during the Centre-Left Government's time in office, social security was extended to previously uncovered categories of the population. In addition, entrance to university by examination was abolished in 1965. Despite these important reforms, however, the reformist drive was soon lost, and the most important problems (including the mafia, social inequalities, inefficient state/social services, North/South imbalance) remained largely untackled. The Italian Parliament voted, in December 1962, a law which created an Antimafia Commission. Any question about the need for such a law
