Thailand’s former prime minister Thaksin Shinawatra has alleged that the election on Sunday was plagued with “irregularities”.
Mr Thaksin, who was ousted in 2006 and lives in self-imposed exile, told the BBC the inconsistencies “worried” him.
The election was Thailand’s first since a military coup in 2014 removed Mr Thaksin’s sister, Yingluck Shinawatra.
Early results saw the pro-military Palang Pracha Rath Party (PPRP) gain a larger share of the popular vote.
But there have been growing complaints about discrepancies in the voter turnout and number of ballots cast. Officials have said there were some cases of “human error” in reporting the data.
Official results will be released in May. bbc
