OxFam are dodgy with their tax affairs too
OxFam aren't squeeky clean over their handling of tax either. They use dodgy methods to get as much money as possible, using techniques that could be seen as evasion if HMRC got off their arse and decided that it wasn't what Parliament wanted when the laws were written. See how they handle GiftAid on donations of non-cash items. Plus they don't really spend that much on the needy, keeping a load for themselves to pay the high salaries of their executives.
