Lithuania's new Prime Minister, Mindaugas Sinkevičius, made regional security and Baltic cooperation his first priority in office, placing calls to his Estonian and Latvian counterparts and meeting Latvia's president in person within hours of his government being sworn in. Sinkevičius' cabinet took its oaths in parliament, the Seimas, on Tuesday, backed by a 75-seat majority comprising the Lithuanian Social Democratic Party, the Democrats "For Lithuania," and the Lithuanian Farmers, Greens and Christian Families Union. The new government held its first cabinet meeting the following day, Wednesday.
