Caretaker Prime Minister Giuseppe Conte has accepted a mandate to form a new coalition with a vow to lead a “more united, inclusive” Italy, a week after the collapse of his government dominated by nationalists.
He said Italy should play a leading role in Europe, a marked change from the policies of the right-wing League.
League leader Matteo Salvini triggered the downfall of the previous coalition.
His partner, Five Star, has now reached a deal with the centre left.
Mr Conte, an independent ex-law professor, had already savaged Mr Salvini in parliament last week, accusing him of creating a political crisis for “personal and party interests”.
After President Sergio Mattarella gave him a mandate to form a new coalition, he said Italy had to make up for lost time as it was in a “very delicate phase”.
“It will be a government for the good of the citizens, to modernise the country, to make our nation even more competitive internationally, but also more just, more supportive and more inclusive.”
Mr Conte has also accused the League leader of having an obsession with closing ports to migrants, and in one of his last acts as interior minister, Mr Salvini refused to allow a charity rescue ship into Italy carrying 100 migrants. The interior ministry has since agreed to allow women, children and sick people off the Mare Ionio.
Parties to the coalition
The anti-establishment Five Star Movement has long been hostile to its new prospective partner, the Democratic Party (PD).
But on Wednesday evening the two parties buried the hatchet. They entered talks last week after Mr Conte resigned ahead of a no-confidence motion tabled against him by Mr Salvini.
One of the stumbling blocks had been Five Star’s insistence on Mr Conte remaining as prime minister.
“We consider it worthwhile to try this experience,” the PD’s Nicola Zingaretti said after meeting the president, with the aim of forming a government to serve until the next scheduled elections in 2023.
“In difficult times like these, shunning our responsibility to have the courage to try this is something we cannot afford,” Mr Zingaretti said.
