ROME, Jan 14 (Reuters) - Italy will announce a new stimulus package worth some 30 billion euros ($36.46 billion) on Thursday, pushing this year's budget deficit significantly higher than previously planned, two government sources told Reuters.

The deficit target will be hiked to almost 9% of gross domestic product from the current goal of 7%, one of the sources said.

The extra spending, to be formalised at an evening cabinet meeting, comes in the midst of a government crisis triggered on Wednesday when former premier Matteo Renzi withdrew his small, centrist Italia Viva party from the ruling coalition.
