"We can't agree to holding a referendum. We will only back a reform which will not require a referendum," S B Dissanayake, the Minister of Social Empowerment, said.
Dissanayake, who is a member of Sirisena's Sri Lanka Freedom Party (SLFP), said Prime Minister Ranil Wickremesinghe's United National Party (UNP) was not in agreement with the electoral reform proposed by the SLFP in the Constitution.
"They do not want to go back to the first past the post system (from the current proportional representation)."
Hakeem said certain parties were trying to change the current proportional representation system with ulterior political motives.
Minority and smaller political parties want the current proportional representation system to continue.
The new Constitution will replace the current executive president headed Constitution adopted in 1978.
