A lot of traditional supporters have been disappointed at the continuing lack of strong direction. Many of those were footsoldiers, who have been departing in their droves, such that quite a few local associations are no longer viable as fighting machines.
Cllr Arthur said that the Conservative Party has lost touch with its core values and he had become disillusioned with the Tory leadership.
Cllr Arthur will remain as Deputy Leader of Horsham District Council and is the fifth councillor to defect to UKIP this week and the 19th defection this year.
