I don't think the Libdems ever have the budget to overspend on anything though. And what has gotten the Tories into trouble is that items haven't been accounted for on either their local OR national accounts (namely the hotel spending). There's creative accounting and there's not even accounting for things at all. Overpending at national level is just a fine compared to overspending at local level being a criminal offence, which makes no sense at all either. Of course, whether prosecutions happen or not, the PR damage is done.
