I see this has turned into an anti-charity thread with falsehoods about charities being peddled (70-80% profit margins, for example).
I don't doubt that some charities are corrupt and some have corrupt people involved. However, the law is clear.
A charity may not distribute its profits. Any excess of income over expenditure must be retained by the charity and used for its charitable purposes.
The trustees (who are the people in charge) may not be paid for acting as trustees.
Where a trustee is paid as an employee or for providing goods or services to the charity, they may not vote on any decisions relating to this payment and the trustees must be able to show that the payment is in the charity's best interests and reasonable for what the charity is getting.
If any trustees are employed or providing goods or services, they must be a minority of the trustees, so if a charity has, say, six trustees, no more than 2 of them can be employed or paid for providing goods or services.
The rules about payment include payments by companies owned by the charity. A payment to a company or person associated with a trustee is treated as a payment to the trustee.
As I understand it from the reports in the press, the Captain Tom Foundation is being investigated because it appears to have broken the law on payments to trustees, in that, since two of the four trustees were husband and wife, payments were being made to a company associated with 50% of the trustees. There are also questions as to whether the payments were reasonable and in the Trust's best interests.
