The UKIP group leader on Cambridgeshire County Council Paul Bullen has lost his seat to the Conservatives.
Mr Bullen, who is also a candidate in the race to be the first elected Mayor of Cambridgeshire and Peterborough, lost out to Terry Rogers in the Warboys and the Stukeleys division.
Only two of the six counties in the Anglia region have so far declared results but the Conservatives are making the early running.
The Chairman of Colchester's UKIP branch has defended the party after a poor showing in this year's local elections.
Just under a quarter of residents in Peterborough have cast a vote for the newly-created post of Mayor of Cambridgeshire and Peterborough.
