An anti-graft activist claims he has uncovered numerous alleged irregularities in procurements for the government's problematic One Tablet Per Child project.
The project has failed to deliver a single tablet to students for the 2013 academic year.
Mongkonkit Suksintaranon, secretary general of an anti-corruption network, accuses there has been bidding collusion and other irregularities in what he labelled as questionable procurements.
He said Shenzhen Yitao Intelligent Control announced that it had secured the tablet contract from the Thai government four months before bidding took place.
The Chinese supplier terminated its contracts with the government earlier this year without delivering any tablets. Another supplier, Jasmine Telecom Systems, also missed delivery deadlines.
By the end of this month, it would have delivered less than 10 per cent of some 400,000 tablets it was contracted to produce since late least year.
Mongkonkit said he wrote to caretaker Education Minister Chaturon Chaisang to raise concerns about the e-auction for the tablet procurement and the suppliers.
“In reply, he has told me authorities are in place to oversee the procurements and address all relevant issues,” he said.
