The British record is just that, it is the recording of an event that was verified in meeting the criteria set down by the BRFC at the time of the event. If Ray Clarke wants to have his record roach removed from the record list he could make a statement that he cheated in meeting the BRFC criteria. For example, if the fish was returned alive to the water, he could say he stuffed it with swan shot before weighing it, or get the person or persons verifying the catch to say they lied, etc.
