More than one and a half million people voted across the East of England in this year's European Election which was a little more than one-third of the electorate.
Turnout across the region was about the same as in the last European election in 2014 although it was down six percentage points in Great Yarmouth to 31.4%.
Turnout in the Eastern region in the European Election
Although the UK voted for its Euro MPs on Thursday, the votes could only be counted on Sunday after the whole of Europe had completed voting.
The Eastern region constituency is made up of the six counties of Bedfordshire, Cambridgeshire, Essex, Hertfordshire, Norfolk and Suffolk.
All the votes were counted in the 45 districts of the region and then collated into a final result in Chelmsford.
The seven MEPs were allocated under a proportional representation system accounting to the share of the vote each party received.
The seven MEPs from the Eastern region are among 71 Euro MPs from the UK.
The European Parliament, which meets in Brussels and Strasbourg, has a total of 751 MEPs from 28 countries.
Britain was due to leave the European Union on 29 March 2019 but that has been extended to 31 October.
