I was giving the reasoning of a Tory MP spokesman, ymf. He was speaking on Newsnight a while ago. But, yes, it must be the coalition's argument and not just that of the Tories. Nice to know that the Lib Dems have some input, but I can't say that the coalition is any more than the Tory Party, so far as I've noticed, now that the original excitement has died down.
Is there a flaw? Gosh, I am surprised !
