The United National Party's (UNP) spokesperson said it was looking at ways of ousting the Sri Lankan president, Maithripala Sirisena.
The country was thrown into political turmoil last month after Sirisena sacked the prime minister, UNP leader, Ranil Wickremesinghe and replaced him with Mahinda Rajapaksa.
"We feel that President Sirisena neither is nor fit to hold his post considering the way he believes and acts and therefore we are focusing on removing him under the article 38(2) of the constitution," the party’s media spokesman Harin Fernando told Colombo reporters.
Article 38(2) states: “ Any Member of Parliament may, by a writing addressed to the Speaker, give notice of a resolution alleging that the President is permanently incapable of discharging the functions of his office by reason of mental or physical infirmity or that the President has been guilty of intentional violation of the Constitution, treason, bribery, misconduct or corruption involving the abuse of the powers of his office, or any offence under any law, involving moral turpitude and setting out full particulars of the allegation or allegations made and seeking an inquiry and report thereon by the Supreme Court."
The UNP is also looking to hold a second demonstration in protest at Sirisena's actions.
Fernando's comments come as Wickremesinghe was quoted by The Hindu as saying that he was still willing to work with Sirisena. Read more here.
