A motion from Lincolnshire Conservatives calling for a referendum on EU membership has been presented in Brussels.
County council leader Martin Hill is writing to David Cameron, calling for a national poll Britain's membership of the European Union in 2014.
County Councillor Ray Wootten took a copy of the motion to MEP Emma McClarkin at the European Parliament.
"I had planned a visit to Brussels to raise concerns from residents and when this motion came along I thought I would take along a copy and present it to Emma McClarkin," he said.
"She fully supported it and she said she would raise the issue with David Cameron."
