On 20 February 1986, faced with South African evidence of corruption, Mathanzima was forced to retire as President, although he tried to claim that he wanted to spend more time dealing with family affairs. Kaiser Mathanzima was replaced as President by his brother, George Mathanzima, who resigned later on because he too had been accused of being corrupt. Kaiser Mathanzima was still described as Transkei's effective leader for a time, but the two soon fell out and Kaiser was temporarily detained in the Transkei gaols in 1987; upon release, he was restricted to Qamata.
