That was between Savithri Gunasekara and Nishantha Wimalachandra who represent the ruling party in the Municipal Council.
The reason for the brawl is UC member Gunasekara secretly filming a discussion that took place at the chambers of a council member.
The other members of the UC voice their protest over UC member Gunasekara's actions to post the relevant video on social media.
The brawl began when UC member Nishantha Wimalachandra approached UC member Gunasekara to voice his protest, while the discussion regarding the video was going on.
