My petition: Certify Sri Lankan Government's committed war crimes

My name is VETHANAYAGAM SANJEEVA THANUSHAN I am a Sri Lankan, currently living in the United Kingdom would like to request the parliament of UK to decide that the Sri Lankan Government had committed war crime and genocide in the last stages of war by the way of killing uncountable innocent Tamils in the North Recently UN decided that the government should investigate the war crimes but we wanted the UK government to pressurise the Sri Lankan Government to implement the decision of the UN and at the same time the government should need to make a decision as this is a Genocide against the Tamils. Evidences in Support of the these Channel 4 reports and other widespread documentations. I say the justice delay is denied therefore I need the actions against the Sri Lankan Government is urgent.
