Norway, despite opposition from hardline Sri Lankan nationalist groups, facilitated peace talks and helped negotiate and maintain the truce.
Bogollagama charged that the ceasefire deal signed between the then Prime Minister Ranil Wickremasinghe and Tiger leader Velupillai Prabhakaran had failed to bring stability and undermined the sovereignty of Sri Lanka
"A piece of paper can never bring stability to a country or the security environment of a country, he said.
"We were reduced from a sovereign state to a nominal state by this agreement and that is what we have corrected now," he added.
The ending of the agreement which limited political engagement of the government to only the Tamil Tigers will also pave the way for other minority parties to also take part in any future talks,
