There were reports that Anupong, at a private meeting with Samak, also suggested that the latter either resign or dissolve the House of Representatives, a source said.
The Anupong-Samak meeting took place after Samak, who was also defence minister, met armed forces' top brass at a Defence Council at the Thai Armed Forces headquarters.
Anupong on Friday also ruled out a coup, saying it was not a way to solve the current crisis.
There was strong speculation Friday evening that a similar advice could soon be extended to Samak by his allies. They had an emergency meeting at Chart Thai leader Banharn Silapa-archa's residence late Friday evening.
The allies discussed a proposal for Samak to resign, instead of dissolving the House of Representatives, according to the sources. However, a TV report said that after the heated debate, the coalition partners agreed to continue backing Samak.
As the People Alliance for Democracy increased nationwide pressure on the government, political attention turned to the allies, whose pressure would be needed if Samak was to be forced to step down.
Deputy Prime Minsiter and senior Chart Thai member Sanan Kachornprasart was said to be the one who "coordinated" the meeting.
Earlier, it had been reported that Banharn was planning a press conference at 9 pm. Then it was reported that he decided to cancel the meeting.
Allies' withdrawal of support would mean the government would virtually collapse. Samak would either have to resign or dissolve Parliament.
Samak's resignation would mean Parliament would have to elect another MP as prime minister.
The present Constitution stipulates that the prime minister must be an elected MP. However, "suspension" of certain constitutional clauses, it is believed, will be enough to pave the way for appointment of a non-MP prime minister if necessary.
