Keheliya Rambukwella, government spokesman criticized UN of having a 'hidden agenda' on Sri Lanka. He said that UN Secretary General Ban Ki-moon's appointment of a panel to violations of international human rights in Sri Lanka was "an attempt to provide oxygen to Liberation Tigers of Tamil Eelam (LTTE)".
The island has been finally successful in wiping out separatist Tamil Tiger guerrillas after decades of ethnic bloodshed.
Rambukwella remarked the statement through a government website.
Ban Ki-moon had set up a three-member panel headed by Indonesia's former attorney general Marzuki Darusman, to look into alleged human rights violations during the final stages of the battle against LTTE in Sri Lanka.
Sri Lanka President Mahinda Rajapakse also had described the UN's latest move as 'unwarrented and uncalled for'.
