The former deputy senate president was sentenced to ten years in prison, while his wife was condemned to six years.
In March, the couple and medical “middleman” Dr Obeta, 50, were convicted at the Old Bailey.
Sonia Ekweremadus, who has a significant kidney problem, sobbed when she was absolved of the same accusation.At a sentencing hearing on Friday, Ekweremadu was sentenced to nine years and eight months in prison, his wife Beatrice to four years and six months, and Obeta to ten years.
Mr Justice Johnson stated to 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.”
The 21-year-old street seller was allegedly to be compensated for donating the organ to Sonia Ekweremadu in an £80,000 private treatment at London’s Royal Free Hospital.
The case marked the first time defendants were convicted of an organ harvesting conspiracy under the Modern Slavery Act.
While donating a kidney is legal, it becomes illegal if money or any material advantage is offered in exchange.
The prosecution claimed the donor was offered up to £7,000 and promised a better life in the UK.
The donor did not understand until his first appointment with a consultant at the hospital that he was there for a kidney transplant, the Old Bailey was told.
