The Samagi Jana Balawegaya (SJB) should undergo changes to face the challenges of new politics and of the new world, its newly elected MP Ajith P. Perera said today. 

"The party should introduce a system of management and should appoint right people to the right positions," Perera told media.

SJB suffered a setback like other parties as it obtained only 1.9 million votes compared 4.2 million obtained by Sajith Premadasa who was it's candidate at the Presidential election.
