President Maithripala Sirisena today hit out at those who criticize his government's attempts to introduce a new constitution by insisting that "we strive for something you do not understand".

Speaking at the national celebration to mark his first year in Presidency, Sirisena said that certain people were making unsubstantiated claims at the constitutional reform programme. He insisted that the special status to Buddhism will not be changed and national security will not be compromised by the proposed constitutional change.

Some MPs of the 'Joint Opposition' have claimed that the new constitution will change the provisions on Buddhism and devolution of power.

Sirisena insisted that the government was seeking changes that people do not see at once. They are intangible, but extremely necessary changes, to ensure lasting reconciliation and peace, the President said.

He insisted that he was ready to embrace any challenge in fulfilling the difficult tasks ahead of him.
