60-year-old Ekweremadu is accused of conspiring to facilitate the travel of a 21-year-old man, David Nwamini, to Britain to use him as an organ donor for his sick daughter, Sonia.

Nwamini, a street trader from Lagos was to be paid up to £7,000 in exchange for a kidney, the Old Bailey heard. Nwamini was promised opportunities in the UK for helping Mr Ekweremadu's daughter.

Ekweremadu, his wife Beatrice, 56, daughter Sonia, 25, and medical "middleman" Dr Obinna Obeta all deny the same charge.

The street trader was falsely presented as Sonia's cousin in a failed bid to persuade medics at the Royal Free Hospital in London to carry out the £80,000 private procedure, the court was told.
