Lockerbie relatives, led by Pamela Dix, who went to 10 Downing Street on 24 October 2009 and handed over a letter addressed to Gordon Brown calling for a meeting with the Prime Minister to discuss the need for a public inquiry and the main issues that it should address.

Alternative theories Based on a 1995 investigation by journalists Paul Foot and John Ashton, alternative explanations of the plot to commit the Lockerbie bombing were listed by The Guardian'''s Patrick Barkham in 1999.
