PAD coordinator Suriyasai Katasila filed a list of complaints and lodged supporting evidence including documents, pictures and video recordings to EC secretary-general Ekkachai Warunprapa.

Suriyasai alleged Thaksin had broken election laws by promising to hand over property that could be measured in monetary value during the election campaign.

Thaksin said at a rally in Ban Pue village, Khon Kaen, that the village had received Bt300,000 from the government's SML (Small, Medium, Large) project and would receive more if he was re-elected prime minister, the document said. And Thaksin's supporters have been giving away T-shirts and headbands, or selling them for less than cost price.

Suriyasai gave Ekkachai one of the T-shirts and a headband. The EC couldn't say the evidence wasn't enough to investigate, Suriyasai said, as photographs existed of Thaksin giving away his own money to students while on the hustings.

He said the EC couldn't employ double standards. It had disqualified former Democrat MP Thanin Jaisamut for attacking his opponents during an election campaign, but what Thaksin had done was worse, said Suriyasai.

Meanwhile, government spokesman Surapong Suebwonglee yesterday rejected accusations by a group of 60 law lecturers from 14 universities that the premier had committed violations of electoral law.

The lecturers on Tuesday released an open letter calling on the EC to disqualify Thaksin.

Surapong denied Thaksin had mobilised state facilities and services while campaigning and said promises made by the caretaker prime minister during a recent campaign rally were part of the ruling party's policy platform.
