The UK Independence Party has gained a foothold in Yorkshire and the Humber, securing its first seat in the region in the European elections.
But Labour topped the poll and took two of the six seats on offer.
The far-right British National Party secured about 8% of the poll and failed to win a seat.
Elected UKIP candidate Godfrey Bloom said: "This is the genuine voice of the people. It's about time the mainstream parties started to get the message."
The results were announced at Leeds United's Elland Road football ground.
Labour secured 26.3% of the vote while the Conservative Party took 24.6%, the Liberal Democrats took 15.6% and the UKIP 14.5% .
The other elected candidates are Timothy Kirkhope and Edward McMillan-Scot for the Conservatives, Linda McAvan and Richard Corbett for Labour and the Lib Dems' Euro MP is Diana Wallis.
Mr Bloom, an economist based in York, said his party had come a long way.
"We are on course for a European superstate and nearly a quarter of a million came out to vote against it in this election," he said.
One of the two Labour members elected, Richard Corbett said he was delighted with the result.
"The people for whom this is a nightmare are the Tories," he said.
Turnout of voters in the region more than doubled from 19.75% to 43.05%.
