Aung San Suu Kyi is attending Myanmar’s parliament as a lawmaker for the first time.
The opposition leader took the oath of office in May after winning a historic by-election. But the swearing-in ceremony took place only as that legislative session ended.
Ms. Suu Kyi was mobbed by reporters as she walked up a flight of stairs into the assembly Monday in the capital, Naypyitaw.
The latest parliament session is expected to see the appointment of a new vice president. Lawmakers are also expected to take up legislation on topics ranging from press freedom to new foreign investment laws.
Ms. Suu Kyi spent much of the past two decades under house arrest during the rule of a military junta.
