The anti-government protest march organised by the Samagi Jana Balawegaya reached Danowita after three consecutive days today.
Addressing the gathering, Leader of the Opposition Sajith Premadasa said an institution to investigate corruption will be established under public mandate.
The Opposition Leader said the institution will investigate allegations of bribery and misappropriation of the countries dollars.
MP Premadasa said he will be true to his word adding during his Presidential campaign he vowed to assign responsibilities pertaining to national security, investigating corruption and preventing bribery to Field Marshal Parliamentarian Sarath Fonseka.
The MP said the power of the SJB is its people while the power of the present administration comes from their wealth.
The Opposition Leader charged the government of using troll farms and adopting tactics used by Nazi Minister of Propoganda Joseph Goebells to spread false information on social media.
The MP said he came across reports on social media stating the SJB would not allow Field Marshal Sarath Fonseka to investigate corruption; adding such claims were blatant lies.
MP Sajith Premadasa reiterated that MP Fonseka will be delegated responsibility pertaining to issues of national security and corruption.
