Rome (dpa) - Italy‘s Five Star Movement (M5S) is one of the most successful anti-establishment parties in Europe, whose main rallying cries are clean politics, direct democracy, euroscepticism and universal unemployment benefits.Founded in 2009 by Beppe Grillo, a stand-up comedian, and Gianroberto Casaleggio, a shadowy internet consultant who died this month, the M5S shot to national prominence after taking a surprise 25 per cent of the votes in the 2013 general elections.The movement defies left-right categorizations, and has shunned alliances with other parties, which it sees as fundamentally corrupt. It is also critical of banks, big corporations, free trade agreements and wants a referendum on Italy‘s exit from the eurozone.The movement‘s defining characteristic is its reliance on internet consultations among its supporters to select its candidates and political priorities, which are communicated online via Grillo‘s blog.But critics have accused Grillo and Casaleggio of using the system arbitrarily and quashing internal dissent. Out of the 163 M5S lawmakers elected in 2013, some 37 have either been expelled or have walked out of the party.In 2014, the M5S hoped for an electoral breakthrough in elections for the European Parliament, which did not come. It won 21 per cent of the vote, against a record 41 per cent for the ruling Democratic Party (PD).The June 5-19 local elections in Rome, Milan, Naples, Turin and other cities will give it another chance to beat the PD. At the moment, the M5S governs only 15 out of more than 8,000 Italian municipalities: the biggest is Parma, which has 190,000 inhabitants.In the EU assembly, M5S lawmakers have formed the Europe of Freedom and Direct Democracy group with the British eurosceptic UK Independence Party (UKIP) and the German anti-immigration Alternative for Germany (AfD) party.The death of Casaleggio, who acted as a behind-the-scenes strategist, has raised questions about the future of M5S, but plans to prepare a younger cadre of party members to take over the leadership have been under way for some time.In November 2014, Grillo said he was "a bit tired" of fronting the movement, and called on lawmakers Alessandro Di Battista, Luigi Di Maio, Roberto Fico, Carla Ruocco and Carlo Sibilia to sit on a five-member advisory panel.Di Maio, a 29-year-old deputy speaker of the lower house of parliament, is seen as the most likely M5S prime ministerial candidate for the next general election, due within the next two years. Grillo has always refused to run for office.
