A group of Samagi Jana Balawegaya (SJB) MPs has made a written call for immediate changes to be carried out by the party and its leader for their victory at future elections.
The 18 handed over their request after having a discussion with their general secretary Ranjith Madduma Bandara, who is expected to hand it over to Sajith Premadasa.
They want a special committee appointed to advise the leader and other seniors on taking decisions with regard to national issues.
Also, seniors should change their approach when dealing with public issues, said the MPs.
