Senate elections were held in Thailand on 29 March 2014 for the second time under the 2007 constitution. Half the senate seats were elected for non-partisan candidates under the first-past-the-post voting system, with voters electing one senator per province. Voter turnout was 43%, down from 56% in the 2008 senate elections and 46% in the February 2014 general elections, which had been boycotted by the opposition,[1][2]
