The International Human Rights Commission (IHRC) joined those pleading for former Deputy Senate President Ike Ekweremadu and his wife Beatrice.
It appealed to the Government of the United Kingdom for leniency in the sentencing of the duo, alongside their doctor, Dr. Obinna Obeta.
The trio were found guilty by Justice Jeremy Johnson Central Criminal Court Old Bailey, London, and convicted in March under the Modern Slavery Act of the United Kingdom.
Ekweremadu, his wife and Obeta would know their fate today when they face the jury for sentencing.
Former President Olusegun Obasanjo, the two chambers of the National Assembly and the ECOWAS parliament have asked the UK Government and Parliament to plead with the court to temper justice with mercy.
IHRC’s Ambassador at Large and Head of Diplomatic Mission to the Federal Republic of Nigeria, H.E. Ambassador Duru Hezekiah made his plea at his Office in Abuja while addressing newsmen.
He described Ekweremadu as a patriotic Nigerian, who has served the Nigerian Senate three consecutive times since 2003.
The IHRC boss reiterated that understanding the Modern Slavery Act of the UK 2015, an Act to make provisions about slavery, servitude and forced or compulsory labor and human trafficking, including provision for the protection of victims; to make provision for an Independent Anti-slavery Commissioner; and for connected purposes, the Nigeria former Deputy Senate President Ekweremadu, 60, his wife, Beatrice, 56, and Obeta, 51, were found guilty of facilitating the travel of a young man to Britain to exploit his organ for his daughter Sonia following her diagnosis which indicated that she required a kidney transplant.
