Thai opposition party members to resign en masse from parliament
Democrat Party spokesman Chavanond Intarakom said the party has about 150 lawmakers in parliament.
The Thai capital has seen massive protests in recent days as anti-government demonstrators call for Prime Minister Yingluck Shinawatra to step down.
"This government is no longer justified to run the country, as this house is no longer justified. Today we resign to express that stance," opposition party leader Abhisit Vejjajiva said.
The rallies have gone without incident for the most part. However, a November 30 protest left five dead when the protesters clashed with Shinawatra supporters.
Protesters and security forces agreed Tuesday to bring an end to the violence as a show of respect for Thailand's revered king, who celebrated his 86th birthday Thursday.
