Under Eligibility Criteria

To be eligible to stand as a candidate for the position of Trustee, you must:

Have not been convicted of an offence involving deception or dishonesty
Have not been involved in tax fraud

That might narrow the field among ukb members
Of course, nobody here will ever have paid a tradesman in cash for "unknown" reasons
