Question to the Department for International Trade:

To ask the Secretary of State for International Trade, if he will set out the proportion of total exports for each region of the UK that went to the EU in each of the last three years for which data is available.

Estimates of the percentage of goods exports by UK region are published by HM Revenue and Customs in its Regional Trade Statistics release:

Experimental estimates of the percentage of services exports by GB region are published by the Office for National Statistics, however they do not cover all services (they exclude travel, transport and financial services) and only cover 2011-2015 and Great Britain. https://www.ons.gov.uk/businessindustryandtrade/internationaltrade/articles/estimatingthevalueofserviceexportsabroadfromdifferentpartsoftheuk/2015

The two datasets above cannot be aggregated together due to differences in methodology and coverage.
