Interior Minister Anupong Paojinda warned governors and local officials on Friday they would be punished if they allowed any more political meetings in their jurisdictions.
The reminder came after the Pheu Thai Party held a meeting in Udon Thani on Wednesday without alerting authorities. Pheu Thai key member Chusak Sirinin said authorities weren't informed because meeting was organised to prepare former MPs for impeachment bids by the National Legislative Assembly.
Gen Anupong told local administrators that a clear directive issued to all districts and provinces remains in effect, barring political gatherings as they could disrupt society and create conflict.
"I have reiterated this policy. If they do not follow it, they will not be warned. In fact, I will punish them myself,'' he said.
Pheu Thai decided to cancel talks in Roi Et and Ubon Ratchathani this week after police, soldiers and ministry officials demanded to attend the gathering in Udon Thani.
Gen Anupong urged Pheu Thai not to use the impeachment issue as grounds to organise meetings, as they could be expanded into political conflicts.
The National Anti-Corruption Commission has asked the NLA to impeach 258 former MPs, most of them Pheu Thai MPs, for misconduct in connection with the 2013 charter amendment to make the Senate fully elected. The impeachment date has not been set.
