ROME (AP) — The Latest on the political crisis in Italy (all times local):

Italian Premier Matteo Renzi says he'll resign now that Parliament has completed approval of the 2017 national budget.

Renzi had offered his resignation two days earlier to President Sergio Mattarella following his humiliating defeat in a government-backed voter referendum on reforms.

But Mattarella told him to stay in office until passage of the budget law, which was done Wednesday afternoon.

Renzi tweeted that he plans to go to the president to resign at 7 p.m. (1800 GMT).

3:35 p.m.

The Italian Senate on Wednesday has approved the 2017 state budget, a step required by the nation's president before he would accept Premier Matteo Renzi's resignation.

It was unclear when Renzi might return to the Quirinal presidential palace to formally resign following the rejection by voters of constitutional reforms he had championed.

On Monday, President Sergio Mattarella asked Renzi to stay in office at least until the critical budget legislation was approved.

The Senate voted 173-108 to pass the budget law, which was put to a confidence vote to speed up its passage.

A huddle was set for Wednesday evening among prominent members of Renzi's Democratic Party, which he leads and which is Parliament's largest party.

8:50 a.m.

Italian Premier Matteo Renzi is opening his final days in office by meeting with his party members, as opposition leaders jockey for position following his resounding defeat in a weekend referendum.

Renzi will address his Democratic Party later Wednesday. The Senate, meanwhile, begins debating the 2017 budget, passage of which will trigger his official resignation.

Italian President Sergio Mattarella had asked Renzi to stay on until the crucial budget law clears before he begins consultations with political leaders on forming a government that can last until new elections are held. Those talks could start over the weekend.

Renzi sorely miscalculated in the runup to the Dec. 4 referendum on constitutional reforms, vowing to resign if it failed. In the end, 60 percent of voters cast "no" ballots.
