The UK currently benefits from the terms of trade agreements, and other trade-related agreements, that the EU has with countries outside the Union. The Department for International Trade (DIT) has set as its second priority “to see a transition of [each of these] agreements to a UK agreement at the point that we leave the EU”. The exact number of EU trade agreements seems to be a matter of some uncertainty. There appear to be around 40 agreements with about 70 countries. Ten of the UK’s top 50 export markets for goods in 2015 were covered by these agreements. The third-country (nonEU) parties to the agreements account for around 11% of UK trade; and the prospective parties to those agreements which are nearest completion or awaiting ratification account for another 25% of UK trade. Unless action is taken, these trade agreements will cease to apply to the UK, without exception, at the point of Brexit in March 2019. In consequence, barriers to trade will be imposed. The EU is also a party to a wide range of other trade-related agreements, covering areas such as regulatory cooperation, aviation, customs procedures, the nuclear industry and agriculture. The number of these too is uncertain, but a suggested total figure for all EU trade-related agreements is 759 (with 168 countries). There is an urgent need for clarity over the number, type, scope, extent and importance of the EU’s trade-related agreements. The Government must reassure us that it has a firm grasp of precisely which agreements will cease to have effect in respect of the UK at the point of Brexit if no action is taken, and what the consequences of that would be.
