Well at this point I am not sure if one should take Blair's word for it - he has enough conflict of interests with Fraud such that I can think of quite a few reasons why he'd want to bury this one (budget, threat of a very public investigation of leaks, etc). And his reputation has been tarnished post G-20 in such a way that one should scrutinize the veracity of his claims on all fronts. Ideally a neutral third party should be the one to verify the claims, or Fraud himself can release those tapes, though somehow I think the latter won't happen. As expected, it turned into a case of he said/she said.
