Coalition parties have been told not to make any further changes to the names in the cabinet lineup as the list is now being checked by Prime Minister Prayut Chan-o-cha, according to Deputy Prime Minister Wissanu Krea-ngam.
Mr Wissanu said on Wednesday the premier has received the full list of potential cabinet ministers and parties joining the coalition government have been informed that "the list will no longer be amended".
"If there is an in-house dispute between the parties [regarding the list], they will have to solve the problem themselves," said Mr Wissanu.
Reports have emerged that some names were vetoed as they were seen to be "influential figures" or being investigated by the National Anti-Corruption Commission.
One of them was said to be Uthai Thani MP Chada Thaiseth from the Bhumjaithai Party, who fielded his younger sister, Mananya, to replace him as deputy agriculture minister.
Mr Chada said yesterday he is happy to serve as an MP and respected the decision made by senior party figures.
Responding to allegations that he is an influential figure, Mr Chada said, "I am not sad that I am seen as an influential figure. For those who vilify me, this is their problem, not mine."
Meanwhile, the Thai Forest Conservation Party, which gained two MPs in the election, appears likely to break away from the coalition agreement after the natural resources and environment ministerial position -- which the party wished to be in charge of -- was reportedly handed to the Chartthaipattana Party.
Damrong Pidech, the party leader, said, "If those handling the cabinet lineup don't trust us, we may have to walk away."
