Meanwhile, the NLA voted to reject impeachment against former Senate Speaker Nikhom Wairatpanich and former House Speaker Somsak Kiatsuranon.

The National Anti-Corruption Commission had recommended the impeachment against the two politicians for their role in passing an amendment to change the composition of the Senate in September 2013. The amendment was later ruled unconstitutional by the Constitutional Court.

Nikhom received 95 votes of impeachment while Somsak got 100, both short of the required number of 132 in the 220-seat NLA.
