The Democratic Alliance/ICOSA coalition took power in the Kannaland Local Municipality in August 2006 when the short-lived ANC-led coalition pact with the DA collapsed. The coalition of the DA and ICOSA collapsed when two ICOSA and three ANC councillors crossed the floor giving the NPP five seats out of nine in the council or an outright majority (the only such council in SA that was governed by this fledgling new party at the time). The DA refused to recognize the new NPP-led council administration as it alleged that the two ICOSA defectors were sacked prior to the floor-crossing window being open and were then challenged in the Cape High Court. As such its former mayor refused to "step down" pending the outcome of the case, creating uncertainty and instability in this beleaguered council.
In the 2011 municipal election, ICOSA regained a plurality in the Kannaland municipality with three seats while the ANC and the DA won two each.
