Four senators have written to Downing Street requesting that Mr Cameron makes time in his schedule to discuss the growing row over the release of Abdelbaset al-Megrahi on compassionate grounds.
BP is facing accusations that it lobbied the previous Government to introduce a prisoner transfer agreement with Libya which paved the way for al-Megrahi’s controversial release. BP has large oil contracts in the north African country.
The Prime Minister has said that he regards the Scottish Executive’s decision to release the terrorist as a “mistake”.
However, Mr Cameron has denied that the decision had anything to do with BP, which is already under intense pressure in America following the oil disaster in the Gulf of Mexico.
Senators Kirsten Gillibrand, Charles Schumer, Frank Lautenberg, and Bob Menendez have requested the formal meeting with Mr Cameron this week. The senators represent New York and New Jersey, where many of the Lockerbie victims lived.
