After a delayed entry into the European Economic Community (EEC) in 1973, the UK institutes a referendum in 1975 but votes to remain in the EEC.
In 2016, Prime Minister David Cameron initiates another referendum and this time the UK votes exit, though the vote is heavily divided across regions (England, Scotland, Wales and Northern Ireland) and age groups.
The details and challenges of exit then start dawning on the politicians as the finalization of the exit leads to drama and comedy.
