Nawaf Salam, head of the International Court of Justice, garnered sufficient support from lawmakers to be designated Lebanon’s next prime minister on Monday, according to Reuters.

Salam’s designation deals a setback to the Iran-backed Lebanese group Hezbollah, which had advocated for the incumbent, Najib Mikati, to retain the position.

Salam, who has led the International Court of Justice since February and previously represented Lebanon as its ambassador to the United Nations, has secured support from several factions, including the anti-Hezbollah Lebanese Forces, a prominent Christian political party.
