The father of one of the Lockerbie bomb victims has urged investigators to consider new evidence which could help clear the man convicted of the atrocity.
Libyan Abdelbaset Ali Mohmed Al Megrahi was jailed for 27 years following the 1988 disaster, when 270 people died as an American passenger blew up over the Scottish town of Lockerbie.
An appeal against the length of his sentence is due to be heard towards the end of the year. A previous appeal against the conviction was refused in 2002.
The new development in the case comes with the publication of a book by a British diplomat's wife, journalist and author Brigid Keenan.
Ms Keenan and her husband Alan Waddams are said to have had dinner with an ex-Interpol agent during which the agent claimed the bombing was carried out to avenge the downing of an Iranian civilian airliner by the US five months earlier.
He alleged that the bombers knew the plane's cargo would go unchecked because of a drug smuggling agreement between the US and a terror group linked to Lebanon.
Dr Jim Swire, who lost his daughter, Flora, in the disaster, said he has written to the Scottish Criminal Cases Review Commission (SCCRC) to alert them to the alleged meeting in Gambia.
Dr Swire said: "I think it could be a very significant story because it relates to events that occurred within weeks or a months or two of the disaster.
In 2003 the SCCRC announced that it had received an application from Megrahi's lawyers requesting it review his conviction.
Dr Swire added: "I presume having taken three years so far the SCCRC must have looked at a lot of evidence already but I thought it was my duty to make sure they had this available. It is hear-say evidence but they might be interested enough to interview the people involved."
