Over the last number of years we have not had the border controls in place. The Single Market has developed and the barriers have been removed to trade. My concern is that we have not been able to measure the complexity of the supply chains, economic relationships, or even the labour and the raw materials and components that are being used, in terms of it being counted. It is much more complex than we are seeing. How can we be sure of the integrity of the data? How much is this being measured in such a way that we can rely on the forecasts and predictions we are making around the impact of Brexit?
