The euro zone has been largely free of its debt crisis so far this year. But the Italian election has changed that. After all the domestic votes were counted Pier Luigi Bersani's centre-left party was neck and neck with Silvio Berlusconi's coalition. Crucially, a protest movement led by comedian Beppe Grillo polled equally well while the current Prime Minister trailed with just 10%. There was no majority in the Senate either and control of both houses is needed to govern.
