ROME--Italy's President Sergio Mattarella has summoned outgoing Foreign Minister Paolo Gentiloni to the presidential palace later Sunday, the clearest sign yet of who might replace Matteo Renzi as an interim prime minister.
The president is expected to give Mr. Gentiloni the mandate to try to form a new caretaker government. If Mr. Gentiloni accepts, he will then start consultations with the other political parties to form his team of ministers.
The government crisis was sparked by Mr. Renzi's resignation after a stinging defeat in last Sunday's referendum on constitutional reform which was voted down by a wide margin.
