WATCH LIVE | Patricia de Lille vs DA in court

Cape Town mayor Patricia de Lille's legal team is expected to conclude its arguments in the Cape Town High Court on Tuesday.

De Lille is challenging the constitutionality of the Democratic Alliance's (DA) cession clause that the party relied on to fire her last month. Her assertion that she would resign from her position after clearing her name in an interview with radio show host Eusebius McKaiser in April cost her her membership. The DA is defending the lawsuit.
