Move Forward Party list MP-elect Nateepat Kulsetasit has resigned as an MP candidate of the party after police arrested her for drink-driving early Tuesday morning.
Ms Nateepat told reporters on Tuesday that she apologised to the public and regretted her actions because she had disappointed people and would not be able to vote for the same-sex marriage legislation that she had pushed for.
She said she had met some friends at around 11pm on Monday and had three or four drinks. She denied she resisted a police request for an alcohol breath test.
It was reported that Ms Nateepat, 46, was stopped at a police checkpoint in Lat Phrao district of Bangkok. An alcohol breath test showed she had 66 milligrammes of alcohol per 100ml of blood, above the limit of 50mg.
Move Forward unofficially won 152 House seats including 39 list seats in Sunday’s election and is currently in the process of forming a coalition government. Ms Nateepat was ranked 27th on her party’s roster of 100 list candidates.
Ms Nateepat said she remained a member of the party.
