Of note is the view that 20m would be a sufficient separation distance to prevent cross pollination with non-GM potatoes. This parameter would be of value in determining fault in a fault based compensation system. Ensuring or restoring a 20m separation would have a cost. At present, the UK authorities have the view that fault based compensation systems for harm done by GM crops are unlikely to meet the needs of public policy.
