This is really awkward for Edwards. He's sensible enough not to dismiss serious matters, and is still middle management with many years to do, but he got himself well out of his depth back in 2013 and has shown that his conduit explanation in his witness statement is far from being true.
No wonder Sir Wyn Williams was impatient to get the first witness out of the way, to have more time for this one.
As ever, when it comess to the post-2012 cover-up, Mark Davies' fingerprints are all over the place.
