Back in 2017 the Lib Dems took Rustington from the Tories, but this time the seat swung hugely the other way and Conservative Alison Cooper was elected.
Four years ago Ian Buckland was elected for the Lib Dems in Littlehampton Town, but this year he stood as an Independent. However this time around it was Conservative David Britton who was elected.
The longest serving county councillor James Walsh was re-elected in Littlehampton East, while fellow Lib Dem returned in Bognor Regis East.
Elsewhere the Conservatives retained all their Arun seats.
With several incumbents stepping down, new Tory count councillors include Trevor Bence (Fontwell), Keir Greenway (Bersted) and John Charles (Felpham).
Mrs Cooper said: “I was delighted that the hard work paid off, and can’t wait to start representing Rustington at West Sussex County Council.
“It is an honour to be elected, thank you to everyone who voted for me and all the support I received in my campaign. A good turnout and a strong majority is a great mandate.”
Mr Bence added: “I am delighted to be endorsed as the county councillor for the Fontwell Division at WSCC . I wish to assure everybody that the green agenda will be my top priority and I welcome the opportunity to drive this agenda forward.”
