Well, that article from a couple of years ago suggests it'll be more like an £8m fine, but the latest report today suggests the panel doesn't feel that a £58m fine is disproportionate, so one completely contradicts the earlier one.
I don't see how the fine can possibly be £50m+ now though, when the precedence has already been set to fine the cheats around £8m.
What's not to understand? The fines are proportional to the SIZE of the overspend.
