Two rival camps contesting Thailand's first election since the military coup in 2014 have both said they are trying to form a coalition government. Early results give the pro-military Palang Pracha Rath Party (PPRP) a larger share of the popular vote. At the same time, the main opposition Pheu Thai party currently has the biggest number of seats in parliament.
But there are growing complaints about irregularities during Sunday's poll and a vote count marred by confusion. The Electoral Commission (EC) is also facing strong criticism for its decision to delay publishing the full results without providing any explanation.
Thailand's complicated electoral system allocates some parliamentary seats according to the number of votes received. Critics say electoral law changes introduced by the military in 2017 are primarily designed to keep pro-military forces in power.
