New Italian Prime Minister Enrico Letta has won his first vote of confidence. He had earlier pledged to reverse an austerity policy he said was killing Italy and focus on jobs and growth.  Italy's lower house of parliament, the Chamber of Deputies, easily passed the confidence vote on Monday by 453 votes to 153. A second vote in the Senate on Tuesday will decide whether the government gets full confirmation. In his inaugural speech on Monday Letta sought to appease his uneasy coalition partners by promising to push for a change in the European Union's austerity policy and foster growth and jobs. Letta also pledged not to raise the sales tax; and to reduce some payroll taxes. He said the government reforms would bring results within 18 months or he would "take the consequences."
