Ike Ekweremadu, 60, and Beatriz Nwanneka Ekweremadu, 55, were charged with conspiracy to arrange a trip for another person to exploit them, namely organ harvesting, police said.
Ekweremadu is an opposition senator in the southern state of Enugu and a former Vice President of the Senate.
Police said they were alerted to the alleged plan after reports of possible offenses under modern slavery law. The injured child has been taken to safety and work is underway to provide additional support.
The couple appeared before Uxbridge Magistrates’ Court in London, where the court was told that they were talking about a 15-year-old boy, according to the BBC.
The prosecution told the court that the Attorney General’s consent was required to hear the case due to jurisdictional issues, the BBC added, and the couple were taken into custody pending their next court appearance on July 7.
Neither Ekweremadu nor his wife were available for comment.
