National Counter Corruption Commission (NCCC) chairman Panthep Klanarongran said the sub-committee had to determine whether the assets and liabilities in Thaksin's financial statements were correctly reported.

He said Klanarong Chantik would head the sub-panel.

Panthep said the panel would also investigate Thaksin's sale of Shin Corp shares to Ample Rich Investment, the company he registered in the British Virgin Islands.

"The sub-committee will determine if there was a real sale," Panthep said.

Thaksin claimed he had sold his shares held by Ample Rich to his children before he entered politics more than five years ago.

Earlier, the People's Network against Corruption secretary-general Veera Somkwamkid and Democrat executive Korbsak Sabhavasu, handed in an appeal asking the NCCC to thoroughly examine the ex-premier's financial reports filed with the agency.

Klanarong said yesterday his panel was likely to investigate whether Ample Rich was owned by Thaksin and to verify who owned the shares in that company.

"If he [Thaksin] didn't report this asset, we will determine if he intended to hide it or not," he said.

However, the panel will not probe the sale of Shin Corp shares to Temasek Holding because it is unrelated to the assets case, he said.
