East Anglia is the most Eurosceptic region in Britain according to a Sky News study, with London holding all of the country's top 20 pro-EU districts.
The top five districts with the highest proportion of Out supporters are in East Anglia - with Tendring, home to the UKIP stronghold of Clacton, coming first on the list.
Coastal areas dominate the top 30 pro-Brexit zones, including North Norfolk, Dover, Torbay, the Isle of Wight, Weymouth and Portland, Thanet, Gosport and Cornwall.
The capital's core of Westminster, Kensington and Chelsea, and the City of London make up the top three districts with residents most likely to vote to remain in the European Union.
In many pro-Brexit areas, agriculture is the biggest industry - and because the EU accounts for more than half of all British food exports, there are more jobs linked to EU trade in these regions, per head of the population, than in London.
The Sky data is calculated by looking at the demographics of each region and the numbers who fall into categories most likely to vote to leave the EU, such as older retired people or younger people struggling to find work.
