Cameron had yesterday given Sri Lanka an ultimatum to conduct a credible probe into the war crimes by March, failing which he would seek an international investigation.
Rajapaksa had promptly rejected Cameron's demand and the Sri Lankan government said it would not conduct any inquiry under “pressure” or allow an independent international probe.
After a historic visit to war-ravaged Jaffna, the first by a foreign head of government since the island's independence from Britain in 1948, Cameron met Rajapaksa Friday night.
