Some political parties and movements have vowed to push harder for either an amendment or rewrite of the 2017 constitution, saying only a fair charter will bring about a free and just election.
"Even after all those past charter-amending proposals ended up being shot down by the Senate, we remain committed to fighting for a new constitution that comes from the public," said Metha Matkhao, secretary-general of the Campaign for Popular Democracy (CPD), a pro-democracy and human rights group.
