The red shirts will on Tuesday's afternoon finalise their decision on the reconciliation road map and the November 14 elections offered by Prime Minister Abhisit Vejjajiva on Monday.
Core leaders, including Veera Musigapong, Jatuporn Promphan, Nattahwut Saikua and Jaran Dithapichai, have positively reacted to Abhisit's peace overtures.
Jaran conceded to having closed-door negotiations before the prime minister outlined his road map to end the stand-off.
Regardless of the response from the red shirts, the government has scheduled May 20 to kick off the reconciliation process by convening a people's assembly for comprehensive reform.
Under the road map, the government calls on all sectors of society to strive for safeguarding the monarchy, activating social reform to ensure justice, upholding press freedom in the constructive manner to prevent divisiveness, forming an independent panel to establish the truth related to violent incidents and activating the charter rewrite to revamp the political system acceptable to all sides.
