Reiterating the need for "progress" on the implementation of the UNHRC resolution by the "end of the year", the UK's Foreign and Commonwealth Office (FCO) said it "will consider all options available to press the Sri Lankan Government to fulfil its obligations."

Responding to a letter sent by British Tamils Forum (BTF) objecting to Mahinda Rajapaksa's UK visit, the FCO said:

"We have consistently called for a credible, thorough and independent investigation into allegations of war crimes committed by both sides during the conflict."

"The UK continues to monitor the situation in the north and east of the country and we consistently raise concerns over access for NGOs and seek further progress on scaling back of high security zones."

"We pressed for and welcomed the resolution on Sri Lanka agreed at the UN Human Rights Council in March, and we have called on the Government of Sri Lanka to play its part in implementing the resolution."

"With international partners, we will continue to encourage Sri Lanka to make early progress, including during the Universal Periodic Review of Sri Lanka at the Human Rights Council in October."

"We expect to see progress by the end of the year and will consider all options available to press the Sri Lankan Government to fulfil its obligations."

In a statement, BTF asserted that the FCO's response to their letter had "exposed the spin" by the Sri Lankan President’s spokesman, Bandula Jeyasekara, who had claimed that Cameron and Rajapaksa "had held a 'cordial' meeting and that the President had briefed the Prime Minister 'on the development in the country."
