Being a minister for 22 months does not confer one with an all-knowing authority on matters actually dealt with by senior civil servants so we need not pay particular attention to what Lilley has to say.
As a trained killer, Peter, you probably spent longer in one foxhole than Lilley did as Secretary for Trade and Industry. It doesn't follow that you have an innate understanding of the underground workings of coal mines or the London Underground.
Please don't respond with, 'Funny you should mention that......'
