ROME (Reuters) - Italy's leaders held their final rallies on Friday ahead of a parliamentary election at the weekend that is expected to be won by a rightist alliance, putting Rome on possible collision course with Brussels.
A trio of centre-left and centrist groups held their closing meetings in different squares across the Italian capital, underscoring their failure to forge a united electoral pact - a decision that has enormously benefitted the conservative bloc.
Opinion polls have all predicted that Giorgia Meloni's nationalist Brothers of Italy group will emerge as the leading party on Sunday and share power with its allies the League, headed by Matteo Salvini, and Silvio Berlusconi's Forza Italia.
Brothers of Italy traces its roots back to a post fascist movement created at the end of World War Two, and although Meloni has sought to project a moderate image, both she and Salvini have been fiercely critical of the European Union, accusing Brussels of interfering too much in national politics.
Ratchetting up tensions at the end of a largely lacklustre campaign, European Commission President Ursula von der Leyen warned late Thursday that Europe had "the tools" to deal with Italy if things go in a "difficult direction".
As other leaders appeared in various squares in Rome and beyond to address their supporters, Salvini staged a brief protest in front of the Commission headquarters in Rome to denounce von der Leyen. "This is shameful arrogance," he said.
A stone's throw away, the one person who could yet spoil the right's ride to power, former prime minister Giuseppe Conte, held the final rally of his 5-Star Movement.
Written off two months ago, after he pulled his support for Prime Minister Mario Draghi and sank the unity government, Conte has revived 5-Star fortunes by promoting its flagship "citizens income" welfare for the poor which the right wants to dismantle.
Pollsters say his relentless message has particularly resonated in the poorer south, where hundreds of thousands live off welfare, and could yet prevent a right-wing landslide.
"The rights' goal is to starve part of the people and that is clearly why the citizens income bothers them," said Mauro Battista, 50, a taxi driver and 5-Star voter.
Barely 2 kilometres (1.2 miles) away, Italy's main centre-left group, the Democratic Party (PD), wrapped up what critics say has been an underwhelming campaign, accusing the right of looking to isolate the country in Europe.
"We have had enough of all this anti-European talk. Long live Europe," PD leader Enrico Letta told cheering supporters.
The crowd was considerably smaller than the one that turned out on Wednesday in the same space for the sole get-together of Meloni, Salvini and Berlusconi, who have tried to downplay their own policy divisions.
"I have a culture and a background that will allow me, when there is disagreement on a certain issue, to call them up, maybe offer them a splendid dinner, and convince them before midnight," Berlusconi said on Friday in Milan.
Earlier, Berlusconi set off a firestorm saying that Russian President Vladimir Putin had been "pushed" into invading Ukraine and had only wanted to put "decent people" in charge of Kyiv. He later said his views had been "oversimplified".
Campaigning is banned on Saturday. Voting runs from 7 a.m to 11 p.m. (0500-2100 GMT) on Sunday, with exit polls released when balloting ends.
The complex calculations required by a hybrid proportional/first-past-the-post electoral law mean it may be many hours before a precise count of parliamentary seats is available.
