evidence: In 2016, Northern Ireland sold £14.6 billion worth of goods and services to Great Britain, which equates to 56% of external sales. External sales are defined as sales by Northern Ireland businesses to destinations outside Northern Ireland, which means sales to Great Britain plus exports beyond the UK. [...] Northern Ireland’s sales to Ireland accounted for 15% of goods and services sold outside of its own borders in 2016, which includes that sold to Great Britain. [...] We found that the Northern Ireland Statistics and Research Agency’s data confirms Nigel Dodd’s claim that Northern Ireland’s "biggest market" is Great Britain. While Dodds claimed that Northern Ireland sends 60% of sales to the UK, the figure is closer to 56%. Comparing this to trade with Ireland, our findings suggest that Northern Ireland is more dependent on trade with Great Britain than it is with Ireland.
