The party of Myanmar's deposed leader Aung San Suu Kyi is set to be dissolved.
Local news outlet Myanmar Now reported the news on Friday.
It said the junta-appointed election commission made the decision against Suu Kyi's National League for Democracy, over what it said was fraud in a November election.
Myanmar Now said the decision was made during a meeting with political parties, that was boycotted by many parties including the NLD.
A spokesman for the junta did not immediately respond to requests for comment.
A spokesman for a pro-democracy national unity government, which opposes the military, also did not respond to requests for comment - though it said it had representatives at the meeting.
Myanmar's military took power at the start of February, after alleging fraud in a November election swept by Suu Kyi's party.
Since then Myanmar activists say more than 800 people have been killed by security forces in protests that broke out after the coup.
