The owners of the site at Caernarfon that the Ministry rejected were willing to sell it, fully remediated and with a commercially acceptable warranty, for a sum of £10 million. Given that the Ministry studiously refused to enter into any negotiations for the site and did not, so far as I can see, ever conduct any soil tests, how is the Minister able to say with such certainty-she has done so on several occasions-that it did not represent value for taxpayers' money?
