A group of SLPP supporters staged a protest near the Samagi Jana Balawegaya head office in Kotte this morning.
They were led by former Mayor of Kotte and Parliamentarian Madhura Vithanage.
The protestors had questioned as to what the SJB MPs had done to strengthen the economy during the previous government.
The SJB said the protestors had thrown rotten eggs at the party office. They had also pasted placards on some vehicles parked outside the SJB office.
