They didn't live up Thatchers character on the Apartheid Affairs, cause she never believe that those sanctions would amount to anything at that time despite herself been opposed to that regime. And no, her son would only go to South Africa in the lates 90's, so there was no conflict of interest as the episode heavily implied at that time. Mandela himself later, praised Thatcher: "She is an enemy of apartheid ... We have much to thank her for." Despite these obvious glaring historical errors, the episode was very entertaining.
