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.
The former deputy senate president received a ten-year prison term, while his wife was given a six-year sentence.
At the Old Bailey in March, the couple and medical "middleman" Dr Obeta, 50, were ruled guilty.
Sonia Ekweremadus, who has a severe kidney problem, sobbed when she was absolved of the same accusation.
Ekweremadu received nine years and eight months in a prison sentence, his wife Beatrice received four years and six months prison sentence, and Obeta was given ten years in prison sentence at a sentencing hearing on Friday.
Mr Justice Johnson told the defendants: “In each of your cases, the offence you committed is so serious that neither a fine nor a community sentence can be justified.”
It was said that the 21-year-old street vendor will receive payment for providing Sonia Ekweremadu with the organ during a $80,000 private treatment at the Royal Free Hospital in London.
It was the first time defendants have been found guilty of an organ harvesting conspiracy under the Modern Slavery Act.
While giving a kidney is legal, it turns becomes a crime if money or some substantial benefit is given in return.
The Old Bailey was informed that the donor did not realize he was there for a kidney transplant until his first consultation with a hospital expert.
