He claimed that British Secret Intelligence Service (MI6) would take-over most of the covert operations that were till recently carried out by CIA to ease anti-American sentiments. Relations between the CIA and ISI went downhill after Raymond Davis shot dead two Pakistanis in Lahore and later given safe passage out of the country.
Islamabad and Washington face two major issues: Islamabad's strong objection to the presence of hundreds of Davis-like CIA operatives on Pakistani soil, and the drone attacks on tribal areas bordering Afghanistan that have caused considerable collateral damage and drawn public ire.
The official said that the two countries have decided to involve a third ally, the UK, a common friend, to take over intelligence operations on both sides of the Pak-Afghan border. During his visit to Pakistan, Cameron was accompanied by Sir Peter Ricketts, the national security adviser, Sir John Sawers, head of the secret intelligence service and Sir David Richards, chief of the defence staff. Army chief General Ashfaq Parvez Kayani and ISI chief Lieutenant General Ahmad Shuja Pasha had separate meetings with their British counterparts.
It has also been learnt that Cameron, who telephoned Prime Minister Yousuf Raza Gilani a day before his visit to Kabul, discussed at length issues related to the British spy agency's take-over of intelligence operations in Pakistan. After a high-level agreement, the three spy agencies decided to work out details of MI6's role in meetings to be held in future to give final touches to the arrangement between Islamabad, Washington and London.
A defence expert commenting on the souring relationship between CIA and ISI said that they can fully trust one another to carry forward the policies of the governments whom they serve. This means that they can be trusted to cooperate when it suits them, and to continue to mislead one another when it does not. He further said that the solution to the war of the spies lies not with the spies themselves, but with those who make the policies they defend.
