Conservative Jacqueline Brockway has won the Lincolnshire County Council seat for Nettleham and Saxilby after claiming almost half of the vote.

In another impressive night for UKIP, Howard Thompson finished third, pipping Richard Coupland of Labour.
There were a total of 2,378 votes cast in a turnout of 28 per cent.
