The party of democracy champion Aung San Suu Kyi has won a majority in Myanmar's parliament, the election commission said this morning, giving it enough seats to elect its chosen candidate to the presidency when the new legislature convenes next year in the country formerly known as Burma.
Ms Suu Kyi's National League for Democracy had been expected take control of parliament since Sunday's nationwide vote.
United Nations Secretary-General Ban Ki-moon and US President Barack Obama had already congratulated her on a landmark victory in the country's first free election in 25 years.
Mr Obama and Mr Ban also praised Myanmar President Thein Sein for successfully staging the historic poll, with the UN chief acknowledging his "courage and vision" to organise an election in which the ruling camp was trounced.
Results have been trickling in since the weekend, and this morning the election commission announced the latest batch of seats that pushed the NLD over the threshold to secure an absolute majority in parliament.
The triumph of the charismatic Nobel peace prize laureate sweeps out an old guard of former generals that has run Myanmar since Thein Sein ushered in a raft of democratic and economic reforms four years ago.
Speaking to reporters last night, White House deputy national security adviser Ben Rhodes noted broad participation by Myanmar's people and a commitment by its rulers to abide by the result.
"This is in many ways a momentous opportunity for the people of Burma," Mr Rhodes said.
"We had been very focused on this election. It is a critical milestone in evaluating Burma's democratic transition."
Mr Rhodes said Mr Obama would meet with the Myanmar president, along with other regional leaders, during his Asia trip this month.
Mr Obama has visited Myanmar twice over the past three years, hoping to make its transition to democracy a foreign policy legacy of his presidency.
In a call with Ms Suu Kyi, Mr Obama "commended her for her tireless efforts and sacrifice over so many years to promote a more inclusive, peaceful and democratic Burma", the White House said.
Thein Sein, whose semi-civilian government took power when the ruling junta stepped aside in 2011, and powerful army chief Min Aung Hlaing said they would respect the result and hold reconciliation talks with Ms Suu Kyi soon.
