Italian President Mattarella rejects Prime Minister Draghi's resignation

Driving the news: Draghi won a confidence vote earlier Thursday on a relief bill to help Italians facing rising energy costs. But the 5-Star Movement, one of the biggest parties in Draghi's coalition, boycotted the vote over a provision in the measure that allows Rome to operate a giant garbage incinerator, AP reports.

• After losing 5-star's support, Draghi said he would resign because "the pact of trust that this government’s actions have been founded on came undone."

The big picture: Draghi accepted a mandate from Italy's president last year to form a national unity government after the government collapsed over a dispute about the disbursement of recovery funds from the EU, Axios' Dave Lawler reports.

• Draghi had said before Thursday's vote that he would interpret a walkout as a rebuke of his unity government, per the Washington Post.

What's next: Draghi is expected to address Parliament next week, per the New York Times.
