NAYPYITAW, Burma -- The head of Burma's military-appointed state election commission said Friday that his agency will consider dissolving Aung San Suu Kyi's former ruling party for alleged involvement in electoral fraud and having its leaders charged with treason.
Suu Kyi's National League for Democracy came to power after a landslide 2015 election victory and won an even greater majority in November's general election. It was set to start a second term in February when the military seized power in a coup, arresting her and dozens of top government officials and party members.
Junta leader Senior Gen. Min Aung Hlaing cited electoral fraud as the reason for the army's takeover, saying "there was terrible fraud in the voter lists." The army-backed Union Solidarity and Development Party, which suffered unexpectedly heavy losses in the election, made similar allegations.
Independent observers dispute the assertions of widespread irregularities.
Political parties were called to discuss planned changes in the electoral system at a meeting Friday. There, Union Election Commission chairman Thein Soe said an investigation of last year's election that would soon be completed showed that Suu Kyi's party had illegally worked with the government to give itself an advantage at the polls.
"We will investigate and consider whether the party should be dissolved, and whether the perpetrators should be punished as traitors," he said.
Asked for United Nations Secretary-General Antonio Guterres' reaction, spokesman Stephane Dujarric said: "Should that happen, that would be a clear step in the wrong direction."
"What we have all been working for, what the Security Council, the international community has been working for, is a restoration of democracy and a restoration of the voice of the people of Myanmar," Dujarric said.
Burma is often called Myanmar, a name that ruling military authorities adopted in 1989. Suu Kyi and other regime opponents have refused to adopt the change, as have the U.S. and Britain.
Suu Kyi's party, which has thrown its weight behind the mass popular movement against the military takeover, has faced constant harassment since the coup, with its members arrested and offices raided and closed.
The junta initially announced that it would hold new elections a year after taking power, but it later hedged and said it could take up to two years. Before the start of democratic initiatives a decade ago, Burma was ruled by the military for 50 years.
Suu Kyi's party also won a 1990 election, but the military stepped in to prevent it from taking power.
Suu Kyi and other members of her government already face various criminal charges that could keep them from running in the next election. Their supporters assert all the charges are politically motivated.
The announced purpose of Friday's commission meeting was to discuss the junta's plan to change the country's election system from "first past the post" to proportional representation.
In first-past-the-post systems, the candidate with the most votes in a given constituency is the winner, while in proportional representation, the share of winning parliamentary seats in an area with several seats is allocated according to the proportion of the vote won by each party or candidate.
Almost all the major parties -- including Suu Kyi's National League for Democracy -- refused to go to the commission meeting, as they regard the body as illegitimate.
Local media reported that almost a third of the parties boycotted the gathering in the capital, Naypyitaw. Many of the 62 attending were pro-military organizations that polled badly in November's election, failing to win a single seat.
After taking power, the military dismissed the members of the election commission and appointed new ones. It also detained members of the old commission, and, according to reports in independent Burmese media, pressured them to confirm there had been election fraud. The new commission declared the election results invalid.
The Asian Network for Free Elections, a nonpartisan monitor, said this week that the results of November's voting were representative of the will of the people, rejecting allegations of massive fraud.
