Okay, I take it back. The BBC did tackle the A4e fraud question on Newsnight last night. If you missed it (as I did) you can catch up on iplayer here 25 minutes in. Paul Mason summarised Eddie Hutchinson's evidence, picking out all the juicy bits. He then showed the 2009 internal A4e report which, he said, they had handed to the DWP only to be told that they weren't interested because they were concentrating on current programmes. Mason said that Hutchinson had been surprised to learn of this report. (He joined the company the following year.)
Emily Maitliss then interviewed Chris Grayling. She wasn't sufficiently clued up about the contracts, but the main points got across. Grayling insisted that the allegations were not about the Work Programme, and that the detailed investigation done by the DWP's audit team and Ernst & Young had found no evidence of systemic fraud.
Maitliss tried the obvious questions. Is A4e a fit and proper company? If this was a fraudulent benefits claimant he would be "down on them like a ton of bricks". Grayling stonewalled, but said that there were "significant doubts" about the evidence and "significant doubts" about Eddie Hutchinson.
So the strategy is clear. Suggest that Hutchinson is a liar.
