Seventh arrest

It's reported today that there has been a seventh arrest in the case of suspected fraud at the Slough A4e office.  Quite why this case is dragging on isn't clear.  Does the evidence point to the fact that at least 7 people must have known what was going on? 

I came across an interesting thread on the Money Saving Expert forums, about clothes for interview.  In the past it was the Jobcentre which would provide the money for new clothes.  Now it appears to be the private contractor.  One would hardly expect any private company (let alone A4e) to cough up large amounts of money.  But in this case, £40 for a new outfit, even from Primark, seems insufficient.  Has anyone got recent experience of asking for money for interview clothes?
