Families of the British Lockerbie bombing victims are to press for further inquiries into the disaster.
The group will call for an independent public inquiry into unanswered questions surrounding the circumstances of the bombing.
They want to spotlight the failure of the intelligence services and the aviation authorities to stop the bomb getting on board.
Several bomb warnings were circulating at the time of the disaster. They included the so-called Toshiba Warning which advised that a bomb hidden inside a radio cassette recorder could be smuggled on to a plane.
The bomb which blew up over Lockerbie killing 270 people was hidden inside a Toshiba radio cassette recorder.
The families claim that some people were advised not to get on to the doomed plane and want to know why their loved ones were given no such warnings.
They are also likely to press for further investigation into who ordered the bombing, which was carried out by Libyan intelligence services agent Abdelbaset Ali Mohmed Al Megrahi.
Al Megrahi was found guilty of mass murder yesterday. His co-accused Al Amin Khalifa Fhimah was cleared following a nine-month trial in Holland.
Previous calls for a public inquiry have been rejected on the grounds that such a move would prejudice the long-awaited criminal trial.
Dr Jim Swire, who lost his daughter Flora in the tragedy, said: "There are many unanswered questions about who ordered this vile act and why our loved ones were not protected from it."
