“Under the circumstances, infighting should stop so we can face outside threats,” Deputy Commerce Minister Nattawut Saikua said in his Facebook message Friday.
The red shirts and the coalition lawmakers plan to hold a series of rallies aimed at countering the anti-amnesty protesters.
Nattawut called for unity among government supporters for what he said was “the fight to safeguard democracy”.
The red shirts are expected to kick off their own political rally at the National Stadium on Sunday afternoon.
Red shirts from Pathum Thani have already organised a public meeting to air their support for the administration and have distributed flyers attacking Democrat Party leader Abhisit Vejjajiva and MP Suthep Thuagsuban for attempting to unseat an elected government.
