"There were only 16-17 people at some stations, especially those in the southern provinces of Chumphon, Surat Thani, Ranong, Krabi, Phuket, Songkhla, Satun, Yala and Pattani," Suthep Thaugsuban said.
The anti-government People's Democratic Reforms Committee (PDRC)'s leader has been at the forefront of months-long protests seeking to oust Yingluck and press for political and electoral reforms.
"After the protesters emerge victorious, the PDRC will take legal action against Yingluck for spending 3.8 billion baht without listening to other people who disagreed with holding this election," said Suthep, a former deputy premier and opposition Democrat Party leader.
He said the Yingluck's government insisted on holding the election to retain power for as long as possible.
Ong-art called on the government to lift the emergency decree imposed in Bangkok and surrounding provinces. Now that the election is over, it was no longer necessary to keep the decree in force.
Anti-government protesters forced cancellation of voting in 45 constituencies. However, Election Commission officials said 89.2 per cent of polling stations operated normally, but results are expected to be delayed.
