While the exact figures are difficult to obtain and as yet, still up in the air, my calculations for the cost of the end of the transition period paint a bleak picture. Between the increased costs to British importers and exporters, the demurrage costs for goods possibly delayed for a fortnight, multiplied by the thousands of trucks crossing the Channel, importers and exporters may be looking at an annual burden of more than £33 billion. The long-term effects of customs clearance could be even more dire, similar perhaps, to self-imposed sanctions.
