The Foreign Affairs Select committee is due to publish a report on human rights next week which is expected to highlight Mr Cameron’s forthcoming trip.
Several MPs on the committee want to use the report to express “regret” at Mr Cameron’s decision to attend. The committee has yet to reach a final decision on whether the concerns will be included in the report.
A source close to the committee said: “There are some people on the committee who feel that it was regrettable that he decided to attend and want to express that. Others feel that as the Prime Minister of the UK it would not necessarily be helpful if he died not go.”
Mr Cameron has pledged to raise human rights abuses with the Sri Lankan President Mahinda Rajapaka following the murder of a British aid worker in Tangalle, on the south coast.
Khurum Sheikh, a 32-year-old Red Cross workers from Rochdale, had been in Sri Lanka to rest after an assignment in Gaza, when he and his Russian girlfriend were attacked by eight men in a hotel bar. One of the men accused of the attack is a prominent figure in Mr Rajapaska’s Sri Lank Freedom Party.
