On Tuesday and Wednesday, Parliament is debating drafts on amendments to the 2017 Constitution..
The leader of the royalist group, Warong Dechgitvigrom, brought his supporters and handed over their petition to the senate representative.
The group objected to all draft charters, whether proposed by government parties, the opposition, or the non-profit organisation iLaw.
Warong slammed the draft charter of iLaw, warning it would destroy the administrative structure of Thailand. Also, he added, the Free Youth pro-democracy group had misled people about the current Constitution.
Warong said that politicians from both the government and opposition, aimed to amend the Constitution for their own benefit. So, the charters drafted by them must be blocked.
After submitting the petition, Warong and his royalist supporters will go to the Office of the Attorney-General to submit another petition for blocking any amendments.
