Thailand holds Senate elections

Polls opened in Thailand Sunday to elect the upper house of parliament in a vote 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. The vote comes a day after tens of thousands of demonstrators took to Bangkok's streets to demand the resignation of Prime Minister Yingluck Shinawatra, who has resisted massive pressure to step down despite months of rallies and a slew of legal moves against her, according to AFP.
