These are the top 6 UK exports to the EU

The EU is the UK"s biggest trading partner 'by far' according to the now infamous government leaflet sent out this week.

The government was criticised when it emerged that it had spent £9 million sending a pro-EU leaflet to every household in England.

Prime Minister David Cameron and a number of other Ministers are campaigning to keep Britain in the EU ahead of a referendum on June 23 known as "Brexit."

The leaflet says that the EU buys 44% of everything the UK sells abroad, and that leaving the EU would create "uncertainty and risk."

It adds that the EU's single market has a customer base of over 500 million, and that EU companies have invested £540 billion ($768 billion) into the UK over the last decade - about £148 million every day.
