UKIP was the winner of the European elections in the Arun district.
The party secured some 40 per cent of the votes cast in the poll last Thursday, May 22.
The district council was declared at 11.15pm on Sunday night, May 25, by the local returning officer Nigel Lynn.
It saw UKIP become the most popular party with 17,913 votes and easily ahead of the Conservatives on 12,824 votes.
This was a reversal of the previous Euro election in 2009 in which the Conservatives beat UKIP into second place.
In the latest poll, both parties were far ahead of third placed Labour, which secured 3,972 votes.
The Green Party came fourth - with 2,872 votes - to push the Liberal Democrats into fifth. The Lib Dems, third in the previous poll, mustered 2,204 votes.
There were 15 parties in all on the ballot paper.
The turnout in the Arun district was 37.8 per cent, slightly down on the number of voters four years ago.
