The ruling Palang Pracharath Party (PPRP) on Wednesday handed down punishments against MP Pichet Sathirachawal for turning against it by allegedly teaming up with the Pheu Thai Party in preparing a censure debate targeting the government.
The punishments include annulment although the ruling party has stopped short of expelling Mr Pichet.
Paiboon Nititawan, the PPRP deputy leader and chairman of the party's committee on law and internal regulations, said the punishments were approved by the panel after two hours of deliberation.
