Wearing orange uniforms, lawmakers from Aung San Suu Kyi's National League for Democracy (NLD) arrived for their first day of work in the administrative capital, Naypyidaw, today.
Suu Kyi entered the cavernous parliament building without making a comment. She took a seat alone for the short opening session which saw the lawmakers sworn in and the appointment of a close ally, Win Myint, as lower house speaker.
Suu Kyi, 70, is barred from being president by a military-written constitution because she married and had children with a foreigner.
She has vowed to sidestep this hurdle by ruling "above" a proxy president, although she has yet to reveal her choice for the role.
While there is no clear schedule for the selection of candidates, it could be within days.
Elected members of both houses and the military will nominate three candidates to succeed President Thein Sein, who retains his post until the end of March.
The new president will then be chosen by a vote of the combined houses.
