Worthing Borough Council should remain under Conservative control at this election but the Lib Dems hope to take at least three seats off the Tories.
Only 12 seats are being contested on May 3, one seat in ten wards and two in Castle.
The Conservatives won power in Worthing in 2004 when all 37 seats were contested after boundary changes. In 2006, the Lib Dems took two seats back from the Tories and they hope to repeat the feat this year and next.
The political split is 23 Conservative councillors, 12 Lib Dems, one Independent Tory councillor and one vacancy, following the resignation of a Lib Dem councillor.
The Greens, Labour and UKIP are all bidding for seats.
