The value of Welsh exports and imports to and from other nations of the UK have been revealed.
According to the Office for the Internal Market (OIM) - which is part of the Competitions and Markets Authority - Wales annually exports £26bn to the rest of the UK (England, Scotland and Northern Ireland), and imports £27bn.
All four UK nations are heavily reliant on services, which make up at least 70% of their economies. However, there are some differences between nations. For example, manufacturing contributes relatively more to the economies of Wales and Northern Ireland while professional and technical activities and financial services contribute relatively more to the economies of England and Scotland.
