The new government, steered by veteran democracy activist Aung San Suu Kyi, has spent its first weeks in power freeing scores of political activists prosecuted under the country's former military leaders.
"All of the 83 prisoners that the president gave amnesty to today are political prisoners and prisoners concerned with political cases," Zaw Htay, the deputy director of the president's office, told AFP.
The former junta's routine jailing of dissidents was one of many repressive policies that garnered support for the democracy struggle led by Suu Kyi and her National League for Democracy (NLD), which swept historic polls in November.
The party is stacked with ex-political prisoners who were jailed for their activism under the former military regime.
