Senator Ike Ekweremadu and his wife Beatrice Nwanneka Ekweremadu will remain in custody until August 4 when their case will be heard.
The real reason they are held without bail is that
Ike Ekweremadu allegedly conspired to arrange or facilitate travel of another person with a view to exploitation, while his wife is charged with arranging or facilitating travel of another person with a view to exploitation, which is a serious crime in the UK.
The couple were not asked to enter pleas, but the court heard they have indicated they will plead not guilty.
They deny the allegations, claim that there was a criminal conspiracy, and will say no exploitation occurred, it was gathered.
Deputy chief magistrate Tan Ikram remanded them in custody ahead of their next appearance at the Old Bailey, for a plea and trial preparation hearing, on 4 August.
The Ekweremadus allegedly treated the man, David like a slave before he escaped to Staines Police Station in Surrey.
