Kilman, 65, is the third prime minister of Vanuatu in three years since 2020.
Bob Loughman was elected PM after the 2020 general election. He was ousted by Alatoi Ishmael Kalsakau following a vote of no confidence and a snap election in October last year.
But Kilman ousted Kalsakau in a no confidence vote on September 4, ending Kalsakau's nine-month reign in power.
