The opposition Pheu Thai Party is considering stepping up pressure on Prime Minister Abhisit Vejjajiva to dissolve Parliament by ceasing to cooperate or refusing to participate in the legislature's functions.
"We should discontinue all of our roles in Parliament as protesting people are now demanding power to be returned to them," said Worawat Ua-apinyakul, a Pheu Thai MP from Phrae.
"We tried our best to propose last week to use Parliament to end the political conflict but the government rejected the suggestion, so it should give power back to the people," he said.
The opposition MPs would not resign from Parliament but just quit working in the lower House, he said.
About 20 MPs and party leaders met at party headquarters to seek solutions for the ongoing political turmoil.
However, opposition whip Wittaya Buranasiri said the opposition would just stop cooperating with the government if the prime minister did not respond to the red-shirts' protest.
A final decision on these two options will not be made until a formal meeting of the party on Thursday, said Panpree Pahitanukorn, a deputy party leader.
Plodprasop Suraswadi, another deputy party leader, said the government should disband the House to give an opportunity to voters to choose a new one to administer the country since the current Cabinet was not legitimate.
"This government is not able to run the country even for a single day from now," he said.
The administration has no other choice because it cannot govern the country any more and nobody will listen to it, Worawat said.
The Pheu Thai Party has 189 seats in the House of Representatives.
