The Supreme Court on Tuesday reaffirmed the Election Commission's ruling to disqualify former House Speaker Yongyuth Tiyapairat as an MP.
The Court found Yongyuth guilty in an electoral fraud case. The Court started reading the verdict at about 4pm and finished at 6pm.
Yongyuth is also revoked of his election rights for five years.
The Election Commission filed electoral-fraud charges against proportionate MP Yongyuth, who allegedly gave money to 10 kamnans in Mae Chan district of Chiang Rai to buy votes for his sister, La-ong.
Earlier reports said if Yongyuth is disqualified, the coalition party would propose that Prime Minister Samak Sundaravej dissolve Parliament.
But if Yongyuth is not disqualified, they would propose a major Cabinet reshuffle, with changes to seven or eight portfolios, to improve the image of the government, the source said. Ministers involved in legal cases would be removed.
If Yongyuth is disqualified, the PPP would become the fourth government party having to face the possibility of dissolution.
