Key Palang Pracharath Party (PPRP) MP Suchart Tancharoen is ready to deal with possible glitches in a parliamentary session to vote for a new prime minister if he is nominated by his party to become a House speaker.
The 2017 charter allows MPs to freely voice opinions without the need to fall in line with their parties' stance, which could play havoc with party discipline.
In his view, this may cause problems for the House speaker as he tries to keep order in the House.
But he said he will try to overcome this problem by sticking to the constitution and meeting regulations.
"I don't want these MPs to be called 'cobras'," he said, referring to renegade politicians who defy party resolutions.
"They just follow the constitution that grants them free expression of opinions and votes,'' he said.
Mr Suchart, who was elected as an MP from Chachoengsao's constituency 3, made the comment as the House of Representatives began to take shape as the Election Commission this week endorsed 349 constituency MPs and 149 party-list MPs.
The endorsement came amid rumours that some MPs may act as "cobras" by shifting sides to vote for a prime ministerial candidate who is not nominated by their parties, including a so-called "outsider PM".
Mr Suchart was speaking as he, together with the first batch of 30 MPs-elect, reported to the Secretariat of the House of Representatives on Wednesday.
The election watchdog endorsed only 349 MPs because it issued an orange card barring Surapol Kiatchayakorn, a Pheu Thai candidate for Chiang Mai's Constituency 8, from running in an election for one year after an allegation emerged that he gave a monk 2,000 baht in cash and a wall clock.
"I believe I was slandered," Mr Suraphol told reporters in Chiang Mai on Wednesday.
"The incident was set up."
Mr Suraphol admitted he offered the monk money in a white envelope but disputed claims in a news report that it bore his name, insisting he wrote nothing.
He petitioned the Supreme Administrative Court to consider his case.
