ROME (Reuters) - Comic Beppe Grillo's anti-establishment 5-Star Movement appears to be stealing momentum from Silvio Berlusconi after a string of scandals that have hit the main political parties just before Italy's election.
Publication of polls is illegal in the two weeks leading up to the vote. But several electoral experts who have seen private surveys told Reuters that Grillo's movement is the only one that is thought to be gaining significantly since the blackout period began.
The 5-Star Movement was at about 16 percent when the blackout started, trailing behind the center-left coalition led by Pier Luigi Bersani on almost 35 percent and Berlusconi's center-right bloc on around 30 percent.
However, analysts say it is thought to have gained in the past week, as a series of high-profile scandals has further discredited the big parties. Berlusconi's potential voting pool is the one where Grillo is gaining most, experts say.
This would stall the remarkable progress that Berlusconi has made since storming back onto the political stage in December.
The progress made by Grillo's young movement of protester and Internet activists as the February 24-25 election date nears has underlined his status as potentially the biggest wild card in the race.
He has ruled out forming an alliance with any of the mainstream parties but could play a decisive role in determining the shape of the next parliament and whether a new government enjoys a strong majority or not.
High profile scandals at Italy's third-largest bank Monte dei Paschi, defense group Finmeccanica or oil major Eni have highlighted close links between the political and business elite and fuelled his maverick message.
The gains by Grillo's movement may favor the formation of a stable government if they come at Berlusconi's expense and hand the center-left a clear victory. But they could also muddy the result in the Senate, where the election law makes winning a clear majority more difficult.
Under Italian electoral law, the coalition or party that wins the biggest share of the vote gains an automatic majority of some 54 percent in the lower house. The Senate is decided on individual contests in the regions, which have varying numbers of seats, based on their size.
The gap between the two main coalitions contending for power has stayed broadly stable, and outgoing Prime Minister Mario Monti's centrist bloc is still in fourth place but sliding, experts say.
Before the blackout period for polls, Berlusconi had made races in the key regions that determine the Senate line-up too close to call, notably the affluent northern region of Lombardy. There is thought to be little change to this picture with less than a week to go before the vote.
The 5-Star Movement's positive momentum is clear even without knowing the trend of the polls. On Saturday, 30,000 turned out in Turin's central square on a frigid evening to hear Grillo speak, several times as many as Berlusconi drew to an indoor rally in Turin the next day.
That Berlusconi is aware of the Genoa comic's charge is suggested by the increasingly hostile rhetoric the four-time premier is using against the 5-Star Movement.
"We made an ugly discovery about Grillo's candidates," Berlusconi said on Sunday in Turin. "We discovered that 80 percent are members of the extreme left."
"There is a very high level of discontent and disgust in Italy with the way the country has been run, and that is the source of Grillo's popularity," said one analyst, who asked not to be named.
Grillo founded his movement three years ago pledging to sweep away the "dead" conventional political parties, which he says are corrupt, inept and wasteful.
He has used corruption scandals in Lombardy and Lazio, the region around Rome - which were both ruled by Berlusconi's People of Freedom (PDL) party - in his stump speeches.
"The PDL says it will not put forward any candidates who are under criminal investigation ... There won't be anyone left," Grillo growled from the stage during a rally south of Rome last month.
