The disruption was planned for later this week when the Parliament was scheduled to debate the national budget.
Jatuporn, a member of a PPP group monitoring the anti-government protests, said if the protesters were successful, the government would have to take action as it meant the People's Alliance for Democracy was trying to topple it.
"The PAD's demand now is to seek a new political system and reject the parliamentary system. Doing so would return the country to the dark ages as well as cause severe confrontations," he said.
Jatuporn said he believed PAD would not lay siege to the Parliament during the noconfidence debate.
The budget debate is set for Thursday and Friday, while the noconfidence motion is scheduled to take place today and tomorrow.
Jatuporn said he would file a complaint with police after a Democrat MP publicised his telephone number so that antigovernment protesters could call him.
His daughter, a primary school pupil, was also threatened, he said.
