I remember us debating it!
It seemed a strange thing to do, when there was already something that could have worked. I got the feeling at the time that the government were hell bent on trying to show they could be world leaders in something, possibly to get one over on a certain political and trade union, but let's not go there. Dare I say it, but every time I hear how we're going to be world beaters at something, I get a rather underwhelming feeling, a feeling that a cockup is imminent. If something works from elsewhere, use it.
