Thais voted on Sunday to elect the Upper House of parliament in a poll that could hold the key to the fate of the Prime Minister, who faces possible impeachment for negligence after months of street protests.
While the Senate is officially non-partisan, in reality the two main political camps are vying for control of the chamber in the absence of a functioning lower House following incomplete February polls.
Prime Minister Yingluck Shinawatra has resisted massive pressure to step down despite months of street protests and a slew of legal moves against her — including over her alleged role in a rice subsidy scheme that could lead to an impeachment vote in the Senate.
Polls closed on Sunday afternoon, according to an election official, who said there was no repeat of the widespread disruption caused by anti-government protesters to a February 2 general election.
