Cameron is going to have to answer the tricky question as to why, given that Cable was forced to withdraw because of bias, he gave the job to Hunt, who was on the record as being equally biased.
Why is it reasonable to claim that Hunt could set aside his personal feelings but impossible for Cable to do the same?
I just have this sense the whole thing was an enormous stitch up that (thankfully) got derailed. Someone set up Vince with the Torygraph to get him of the case because they knew he was biased against the Murdochs (though ironically probably would have given them impartiality, which might have seen the deal through at least in some form), then they put a man in charge who was itching to sign on the dotted line but (crucially) this wasn't known by the public. As reward, Dave and his policies would have got an easy ride in the Murdoch press and a decent chance of re-taking No. 10 - probably as a solo act when The Saahn et al blame the LDs for everything in the run-up to the next election. And next on the list of Murdoch's demands would have been the proper NHS-reform-level dismantling of the BBC so Sky could move in and sew up the whole shebang.
If the phone hacking story hadn't hit when it did, I seriously think this country would be well on its way to being considerably shitter.
