Why Did Nelson Mandela divorce Winnie Mandela?

Answer 1

Mr. Mandela announced his separation from his wife in 1992, at the time speaking of her with great tenderness and affection. But within months, Mr. Mandela testified in court, a newspaper editor had shown him a letter that Mr. Mandela said showed his wife was being unfaithful. It was then, he said, that he decided they could never be reconciled.During most of his testimony on Monday, Mr. Mandela described his disappointments in the marriage and his suspicions of Mrs. Mandela's relationship with the junior colleague, Dali Mpofu. Taking the stand again today, Mr. Mandela was often generous in praising his wife's efforts while he was in jail. He agreed that she had suffered a great deal.

Answer 2

I heard somewhere that Winnie cheated on him while he was in prison and that she had a lover when he got out, so they divorced.
