Another week, another revolution. Muammer Gaddafi of Libya may soon become the third Arab president to be swept from power in little more than a month.
Until a few years ago, his toppling would have been greeted with delight in western capitals. But in recent years, the Libyan leader has been recast as a reformed sinner, an ally in the “war on terror” and a valued business partner. His current travails should be a cause of justified embarrassment – not least in London – since Britain has led the way in the attempted rehabilitation of Col Gaddafi.
