Lockerbie bombing: will we ever know the truth?

[This is the headline over a report published today on the ITV News website. It reads as follows:]

A former British ambassador to Libya says he's not convinced questions will ever fully be answered about the Lockerbie bombing.

It's a month since Scottish prosecutors announced they want to speak to two Libyan suspects in connection with the downing of Pam Am flight 103 in 1988 which killed 270 people:

I think we will probably never know the truth, I would say one major reservation, or exception is that, I could imagine there might be a deathbed confession.

Someone who was involved might on his deathbed tell the story, so to speak."

– OLIVER MILES, FORMER BRITISH AMBASSADOR TO LIBYA

Lockerbie bombing: 'if it was Libya, it was Gaddafi'

Throughout the Lockerbie bombing investigation, questions have been raised about the involvement of Abdelbaset Al-Megrahi, who was convicted of the crime.

Oliver Miles spent a short time as British Ambassador to Libya in 1984, and he isn't certain Libya was involved at all.

But he says if the country was involved, it was certainly organised at the highest level:

Don't forget that Abdelbaset Al-Megrahi, who was convicted of the crime, was convicted of conspiracy. No-one imagines that he acted alone.

There must have been a team, if he was part of it, it was a Libyan team, and if it was a Libyan team, it was Gaddafi."
