Thaksin vows to bare all about his opponents on Thursday

"I have to shake things up in order to separate the black from the white," he said in his phone-in to the red-shirt crowd in Phitsanulok on Tuesday's night.

He said his silence did not bring about peace as he had previously hoped.

He began his 10-minute speech by thanking his Phitsanulok constituents for their continuing support.

He praised Phitsanulok MP Niyom Changpinit for loyalty and lamented that another MP Monchai Wiwathanart deserted him to join the coalition Social Action Party.

He pleaded that only Thai people could help him return to his homeland. He said he would devote his time to lead the country as a show of gratitude in return for the people's help to bring him back.

He said his leadership brought about a thriving democracy and a strong government, hence causing resentment to his opponents who stood to gain from the weak political system.

He said the country has plunged to a lowest depth since ousting him from power. He claimed his return could help to restore democracy and advance the country forward once again.

Although he did not make any swipe at the Privy Council like in the Sunday's phone-in, he said one of the coup leaders, General Saprang Kallayanamitr, decided to join in the seizure of power because of his fear to be sacked.
