The five leaders of the PAD said Surayud Chulanont should reaffirm his resolve to root out corruption - to dispel doubts he had a secret agreement "to go soft" on Thaksin.

The five also hinted they might revive street protests if Surayud failed to heed their demand.

"Surayud's activities have cast doubts that he might have made a deal with the old regime," PAD leader Phipob Thongchai said.

Another PAD leader, Sondhi Limthongkul, said Surayud should adjust his stand by issuing a Cabinet resolution requiring every minister to cooperate with graft probes against Thaksin and the ousted government.

Sondhi also urged the term of the Assets Examination Committee be extended for one or two years - to completely "finish off" the Thaksin regime.

PAD leader Chamlong Srimuang said although street protests were not appropriate at this juncture, the PAD would closely monitor the government and might rally again if it deemed this necessary.

Chamlong said the government should strive to achieve tangible results for political reform and media freedom.

PAD leader Somsak Kosaisuk said Surayud would have to reinvent his leadership, or make a graceful exit.

Speaking collectively, the PAD leaders condemned the signature campaign against General Prem Tinsulanonda, president of the Privy Council.

At the press conference held by its five leaders, the PAD released a statement criticising the junta and the government for failing to live up to public expectations after the coup.

The statement was critical of the failure to punish the Thaksin regime for corruption,

causing social divisions, interfering with independent organisations and offending the monarchy, which the junta cited as justification for the coup.

Even though the graft probes against the ousted government had started to show some results, it said progress was too little and too slow.

It said the government and the junta had no tangible achievements "because of the lack of unity".
