Italy: political instability? Real or perceived?

Italy experienced a political system during the post war period which many have defined as a 'particracy' of a 'polarised' kind. This produced a permanent one party government (run by the Christian Democracy) along with a one party opposition (the Italian Communist Party). There was no alternation in government which subsequently brought on other difficulties not to mention a 'deficit in democracy'. The system was defined by some as being 'blocked'. With the end of the Cold War in 1991 and the political crisis which followed soon after (in 1992-94), changes occurred to the Italian political process. Traditional parties that had dominated the political process ceased to exist or radically changed. New parties emerged including Forza Italia, the party of the current Prime Minister, Silvio Berlusconi. Corruption revelations uncovered a systemic wholesale level of political corruption cutting across most parties and factions. Changes occurred as a result of these new political developments. In part there were specific reforms to the political machinery such as electoral reform. In addition the political culture changed which began to see a bi-polar political alternation of centre left versus centre right. Did these changes produce a different, more stable Italy? Were these changes of a kind which produced a new political system, a new republic? Have the fundamental weakness of the Italian political system been overcome?
