Oops, we shouldn’t have let him go.

That’s what the new British Prime Minister is expected to tell President Obama when he makes his first official visit to Washington, D.C., where he will discuss BP and the release of Lockerbie bomber Abdel Baset al-Megrahi.

PM David Cameron will tell Obama the convicted terrorist’s early release was “wrong,” according to London’s Telegraph, but the newly elected Tory will point the blame squarely on Scotland and the previous Gordon Brown’s administration.

“The Prime Minister’s view is that the decision to release Megrahi was wrong and he deeply regrets the pain that his release has caused,” a spokesman said. “However, it was a decision for the Scottish Executive alone.”

But reports suggest Cameron will stress to the President that the current British administration had nothing to do with the decision, and he will also insist that a deal with BP was not a factor.
