MILAN, Sept 30 (Reuters) - Italy's bond yields soared on Monday amid political chaos after ministers in Silvio Berlusconi's centre-right party pulled out of the governing coalition headed by Prime Minister Enrico Letta.
Rome's 10-year bond yields rose by 31 basis points to 4.73 percent while the spread versus German Bunds widened to 304 basis points, hitting the widest since end-June.
On Sunday night Letta said he would go before parliament on Wednesday for a confidence vote with the aim to avoid snap elections.
