The Central Criminal Court, Old Bailey, UK, has sentenced Ike Ekweremadu, former deputy senate president, to nine years and eight months in prison.
His wife, Beatrice, was handed four years and six months jail term during the sentencing on Friday.
The duo were sentenced to prison after being found guilty of organ harvesting.
On March 23, the jury pronounced a guilty verdict on the senator, his wife, Beatrice, and Obinna Obeta, a doctor who acted as the middleman.
The jury held that they conspired to bring the 21-year-old at the centre of the matter to London to exploit him for his kidney.
The verdict is the first of its kind under the Modern Slavery Act 2015 of the UK.
Ekweremadu, 60, his wife Beatrice, 56, and 25-year-old daughter Sonia were accused of conspiracy to bring the man to Britain from Lagos for his Lagos.
The couple, along with medical “middleman” Dr Obinna Obeta, 50, were found guilty in the Old Bailey in March.
In a judgment on Friday, Ekweremadu was sentenced to nine years and eight months’ imprisonment, his wife bagged four years and six months in jail while the medic got a 10-year jail term.
