Grillo says right-left coalition 'would last 7-8 months'
'We'll keep it under control' says protest-vote winner26 February, 13:19
But he said they would not last long.
"They'll make a grand coalition between (centre-left leader Pier Luigi Bersani's) PD and (ex-premier Silvio Berlusconi's) PdL," said Grillo, who sucked votes from right and left to unleash his promised 'tsunami' on Italian politics.
"But we're the obstacle," said the rabble-rousing comic, whose movement is third in both houses of parliament.
"They can't carry on any more, let them put their minds at rest. "They'll be able to go on for seven or eight months, to cause a disaster," he added.
Although pundits see a grand coalition to pass essential reforms as a long shot, Grillo pledged that throughout its short term, "we'll try to keep it under control".
