Corruption probes at three major companies have hurt corporate Italy's image with investors and revived memories, just a week before an election, of the scandals that devastated Italian politics in the 1990s.
Defence firm Finmeccanica, oil group Eni and Monte dei Paschi di Siena, the world's oldest bank and Italy's third largest, all face judicial probes into crimes ranging from bribing foreign officials to accounting fraud.
"We're facing something very like Tangentopoli," outgoing Prime Minister Mario Monti said on Friday, referring to the "Bribesville" scandals 20 years ago. A technocrat appointed in a crisis in 2011, Monti is now campaigning on a centrist ticket.

"A week before the vote, citizens are heading for the ballot box through the rubble of a new Tangentopoli," it said in a front-page editorial under the headline "Sins of the Elite."
Weary of corruption, Italians might welcome a crackdown but with an election looming, many have been quick to spot the party connections of some of the major companies involved and to suspect political motives, despite denials from the judiciary.
"Finmeccanica has been under the spotlight for a good 18 months and suddenly there is an arrest," said Luca Caprai, founder of Cruciani, a maker of fashionable macrame bracelets.
"If this is the beginning of a clean-up, it will be
