"According to confidential correspondence obtained by The Times,

ministers urged the Scottish government to consider returning Abdul Baset Ali al-Megrahi to Libya under a prisoner transfer deal in an apparent breach of a decade-old pledge.

A former Cabinet minister and two sources close to talks over the handover of suspects in 1999 told The Times that Robin Cook, then Foreign Secretary, promised Madeleine Albright, US Secretary of State at the time, that anyone found guilty would serve their sentence in Scotland, where the airliner exploded with the loss of 270 lives.
...
Lord Falconer of Thoroton, the Lord Chancellor, made reference to the deal — to which Libya also agreed — in a letter to Alex Salmond, Scotland’s First Minister, in June 2007. “Libya agreed prior to al-Megrahi’s trial that anyone convicted of the Lockerbie bombing would serve their sentence in Scotland,” he wrote. Britain had reminded Libya of this through diplomatic channels, he said.

The position was reversed two years later when the Libyans applied for al-Megrahi’s transfer. Ivan Lewis, the Foreign Office minister, told the Scottish government that Britain had never provided a “definitive commitment” to the US because it had not wanted to “tie the hands of future governments”.

The disclosure casts doubt on Britain’s insistence that it did not interfere in the devolved Scottish government’s decision last week to let al-Megrahi return to Libya. It also explains the Obama Administration’s anger.
Number one: Screw you, England and Scotland. And every one of your miserable little syphilitic socialist politicians and useful idiots involved in this.

Number two: Obama's 'anger'? You mean his "We're disappointed" speech that showed all the real feeling of a bad actor on stage? It wouldn't disappoint me if he'd known something about this, given his bending over for various islamic governments and tyrants.
