David Cameron's reference to the Megrahi release in his conference speech (courtesy of the Caledonian Mercury) -
"There are some red lines which we must never cross...the sight of that man responsible for the Lockerbie bombing being set free to get a hero’s welcome in Tripoli. No. It was wrong. It undermined our standing in the world. Nothing like that must ever happen again."
Leaving aside the irritating Blair-like 'stream of consciousness' party trick of trying to make it sound as if the sheer gravity of the subject has only just struck him mid-passage, it has to be said that Cameron is moving on to very, very dangerous territory with this rhetoric. It simply isn't possible for London politicians to credibly claim that they "respect" the devolution settlement unless they also accept that decisions that they personally feel are wrong not only can happen again, but almost certainly will, and indeed should. The powers transferred under the Scotland Act were not conditional upon being used in a way consistent with arbitrary "red lines" dreamt up by a Tory leader to win cheap applause at his party conference.
Was it legitimate for Cameron to attack his political opponents for a controversial decision? Absolutely. But to suggest that it must 'never' be 'allowed' to happen again, in order to protect 'our' interests...well, that sounds suspiciously like a threat, and one rooted in the hubris of an almost colonial mindset.
