While claiming that the UNHRC Chief’s report ahead of the HR Council will give an assessment of Sri Lanka’s progress, Britain has reiterated that if a credible domestic process has not begun properly by March it would use its seat on the UN Human Rights Council to call for an international investigation against Sri Lanka.
 

Minister of State, Foreign and Commonwealth Office Hugo Swire told in Britain’s Parliament on Thursday, "We are regularly discussing Sri Lanka with a range of international partners in the run-up to the next session of the Human Rights Council in March."

He also said:

“As the Prime Minister said in his statement to Parliament on 18 November 2013, Hansard, columns 959-61, we will continue to press the Sri Lankan Government for credible, transparent and independent investigations into alleged war crimes. We have made clear that if a credible domestic process has not begun properly by March we will use our seat on the UN Human Rights Council to call for an international investigation. We are regularly discussing Sri Lanka with a range of international partners in the run-up to the next session of the Human Rights Council in March. The High Commissioner for Human Rights' report ahead of the Human Rights Council will give an assessment of Sri Lanka's progress.”
