Thai polls cast political uncertainty

Thailand is set to hold a general election on March 24, its first since a military coup brought down a government under former Prime Minister Yingluck Shinawatra in 2014.

General Prayuth Chan-ocha, who seized power in 2014, will be running in the elections under the Palang Pracharat Party and is considered a shoo-in for the premier's post.

According to the new constitution enacted by Prayuth's administration, the prime minister must obtain majority support from the 500-seat House of Representatives and the 250-seat Senate.

While members of the lower house will be elected, Senate members will be composed of military appointees. The Senate will then select the next prime minister.
