According to the BBC private schools may lose their chariable status if they cannot show that they offer genuine benefits to wider society. Failing to establish that they are not "exclusive clubs" and failing to show that they are "outward looking and inclusive" will mean having to forgo the financial benefits and enhanced reputation that comes with recognition as a charity.
Mmmmmm .... By the same criteria I can think of lots of churches who should be looking over their shoulder lest the charity man come a knocking. Or is that the hand of God at the church door?
