UDD core leader Jatuporn Prompan on Friday said he and two other red-shirt leaders, Nattawut Saikuar and Veerakarn Musikapong, would co-host the Truth Today political talk show which is being revived.
The programme will relaunch on Saturday and then air from 9.30 to 10.30pm on weekdays, Mr Jatuporn said.
The programme was first broadcast in 2008 during the Samak Sundaravej government. The programme was axed in 2009 when Abhisit Vejjajiva was prime minister.
The UDD will hold a mass rally in Ayutthaya province on Tuesday, Constitution Day, in a show of force to protect the elected government, UDD chairwoman Tida Tawornseth said yesterday.
The UDD leader lashed out at the People's Democratic Reform Committee protest for being anarchic.
Protest leader Suthep Thaugsuban had led supporters in seizing government offices and intimidating the media and had almost led the country into a state of chaos, Ms Tida said.
Mr Suthep's proposal to invoke Section 7 of the constitution, which would lead to the installation of a royally appointed prime minister and cabinet, was an attempt to use 100,000 votes to nullify the legitimacy of the votes of 15 million, Ms Tida said.
In Nakhon Ratchasima, a group of red shirts, carrying placards with messages of support for Prime Minister Yingluck Shinawatra, gathered in front of the provincial hall yesterday. The group was led by former transport minister Thawee Kraikupt, former Ratchaburi provincial councillor Suthat Srathongkaew and Sakol Khunapitak, kamnan of tambon Suan Pueng.
Meanwhile, an anti-government group staged a rally at that Thao Suranaree Monument on Friday. No violence occurred.
Anuwat Thinnarat, chairman of the UDD's northeastern network and the Nakhon Ratchasima red-shirt network, said Mr Suthep's threat to escalate his protest to oust the government would ignite more tension in the country.
In Udon Thani, Khon Rak Udon Club chairman Khwanchai Praipana, said leaders of red-shirt networks in 20 northeastern provinces have monitored the anti-government movement in Bangkok.
Mr Kwanchai said he believed national police chief Adul Saengsingkaew could control the situation.
He said he had not yet decided whether to mobilise red shirts to join the UDD's mass rally on Tuesday, as he was preparing to hold another rally in Udon Thani.
