The Election Commission has set March 7 for a by-election in constituency 3 of Nakhon Si Thammarat, following the disqualification of Thepthai Senpong of the Democrat Party by the Constitutional Court.
The EC has scheduled candidate registration for Feb 11-15, from 8.30am-4.30pm.
The Constitutional Court on Jan 27 announced the termination of Mr Thepthai's MP status.
The decision was based on the Nakhon Si Thammarat Court's ruling in August 2019, sentencing Mr Thepthai and his brother Manote each to a two-year jail term and a 10-year-ban from politics for vote-buying during the election of the provincial administration organisation chairman in 2014.
Mr Thepthai fought to keep his MP status on the grounds the case was not finalised. He and his brother are on bail pending a ruling from the Appeal Court, scheduled for March 25.
The Constitutional Court rejected his argument, saying the ban from politics ordered by the Nakhon Si Thammarat court meant he had not been qualified to stand in the general election.
