UKIP claimed two of the five East Midlands European parliamentary seats with the biggest vote – and topped the poll in all seven Lincolnshire districts.
In South Holland, the UKIP vote was 10,408 – more than 4,000 ahead of the Tories on 6,303.
The Tories also claimed two East Midlands seats and Labour one.
It was a disaster for the Lib-Dems as their vote fell behind The Green Party and they lost sitting member Bill Newton-Dunn (72).
Elected were: Roger Helmer and Margaret Parker (UKIP), Emma McClarkin and Andrew Lewer (Conservative) and Glenis Willmott (Labour).
Across the East Midlands, UKIP polled 368,734; the Conservatives 291,270, Labour 279,363, the Lib-Dems 60,773, the Green Party 67,066, Independence from Europe 21,384, British National Party 18,326, English Democrats 11,612 and Harmony Party 2,194.
