New President Htin Kyaw and two vice presidents have taken the oath of office in Myanmar, starting the formal transfer of power to the first civilian-led government in over five decades.
Myanmar has been under military or military-dominated rule since a coup in 1962, and the elections in November which brought the new government to power were the first openly contested polls since 1990.
Htin Kyaw is a close advisor to Aung Sang Suu Kyi and longtime member of her National League for Democracy party.
Two vice presidents, one of them a military nominee, also took the oath of office in the parliament in Naypyitaw.
Suu Kyi, who is also expected to be sworn in on Wednesday, is set to take the post of foreign minister, along with possibly three other cabinet roles, according to media reports.
Htin Kyaw takes over from former general Thein Sein, who has led the country since 2011. Under Thein Sein, the government set in motion reforms that have opened up the once-isolated country to the outside world, including to foreign investment.
Several key portfolios in the government, including defence, are reserved for the military.
