All 16 UKIP councillors on Lincolnshire County Council have refused to sign an anti-racism declaration.
Labour’s Rob Parker presented the document to ensure all Lincolnshire residents are treated equality and have access to the same services.
But Chris Pain, leader of the county council’s UKIP group, the official opposition, told today’s annual meeting of the council: “I cannot support this document.
“It actually pushes forward the chance of multiculturalism, one of the fundamental things that’s wrong with our society.
“UKIP’s stance is not racist.
“Our stance is on space and space alone.”
The motion was passed by 60 councillors who voted for it, with 16 abstentions from UKIP.
The party’s own motion to reduce the council newspaper County News to a single yearly issue to cut costs failed.
Cllr Pain had earlier pressed the council to reduce the amount of money spent on translators in Lincolnshire.
Saxilby ward member Councillor Jackie Brockway, Conservative, said: “I’m very concerned that there’s a theme developing that seems to be attacking the vulnerable and we need to careful about that.”
Cllr Hill said costs had already reduced from £54,000 to £43,000 and that translators perform important roles in schools and law courts.
Liberal Democrat John Marriott said: “I would hope our colleagues from UKIP come up with some more practical solutions as to how local government will survive.”
The meeting officially saw council leader Cllr Hill, his executive and committee heads appointed.
After last month’s election, the Conservatives lost overall control. Thirty-six Tories are now in a coalition with three independents and three Lib Dems.
UKIP has 16 seats, there are seven independents in opposition and 12 Labour councilors.
