Sinkevičius, a long-serving municipal politician from the central Lithuanian town of Jonava, is the third Social Democrat to serve as prime minister since the party won the 2024 parliamentary election. He replaces Inga Ruginienė, who resigned last week after the ruling coalition was reshuffled.
"I will strive to be a Prime Minister who unites rather than divides, who listens and is not afraid to make decisions," Sinkevičius told parliamentarians.
