The man at the centre of the investigation into the disappearance of Madeleine McCann has lost a court appeal to have a separate jail sentence overturned. Christian B had challenged the validity of a European arrest warrant because it cited a drugs conviction but not a rape charge. His appeal came even though Germany had obtained Italy’s agreement for his extradition to be prosecuted and tried for rape and extortion in 2018. Christian B – whose full name cannot be reported for legal reasons – was revealed as the prime suspect being investigated by a German prosecutor earlier this year. The prosecutor believes Madeleine is dead.
