Ike Ekweremadu, the former Senate President, his wife Beatrice, and Doctor Obinna Obeta have all received prison sentences for their roles in the organ harvesting allegations that a UK court brought against them.
While his wife received a six-year prison term, the former vice president of the Senate received a ten-year sentence.
In March, the Old Bailey found the couple and medical "middleman" Dr. Obeta, 50, guilty.
Sonia, the severely kidney-impaired daughter of the Ekweremadus, sobbed when she was absolved of the same accusation.
In a Friday sentencing session, Ekweremadu was given a nine years and eight months in prison sentence, his wife Beatrice received a four years and six months in prison sentence, and Obeta was given a ten years in prison sentence.
"In each of your cases, the offence you committed is so serious that neither a fine nor a community sentence can be justified," Mr. Justice Johnson told the prisoners.
In an £80,000 private treatment at London's Royal Free Hospital, it was claimed that the 21-year-old street vendor would receive compensation for giving the organ to Sonia Ekweremadu.
In this instance, defendants were found guilty of a conspiracy to steal organs for the first time in accordance with the Modern Slavery Act.
While giving a kidney is legal, doing it in exchange for cash or another substantial benefit is against the law.
According to the prosecution, the donor was promised a better life in the UK and up to £7,000.
The Old Bailey was informed that the donor was unaware that he was going to donate his kidney until his first medical consultation.
