It has suddenly become very clear that, seven years after the Foreign Secretary delivered his warning, the Hague doctrine has been abandoned. Over the past few days, though, without the knowledge, let alone assent of a bemused Mr Hague, a series of Cabinet ministers have articulated anti-European sentiments. First to do so was Theresa May, now being talked of as a potential Conservative leader.

Exactly how she proposed to do this was never explained.
