Mr Puchong said according to unofficial reports on the Feb 2 election, of the total of 44,649,742 eligible voters, 20,468,646 or 45.84% turned out to cast their ballots.
The figures did not include eligible voters of nine provinces where voting was cancelled - Songkhla, Trang, Phatthalung, Phuket, Surat Thani, Ranong, Krabi, Chumphon and Phangnga.
The province with the highest turnout was Lamphun with 241,209 (72.80%), followed by Nong Bua Lamphu with a turnout of 277,018 (72.50%) and Bung Kan with 213,627 (70%.).
Asked about election management commissioner Somchai Srisuthiyakorn's offer to accept responsibility for not being able to hold voting at more than 10,000 polling units, and to accept transfer to another position, he said the EC chairman and all other EC members unanimously concluded that Mr Somchai had acted responsibly and effectively performed his duty in a difficult situation.
He was asked to continue to be in charge of election management, Mr Puchong said.
