This case, Operation Grange, has already cost the UK tax payer £12.5 million since it was launched in 2011. Convicted paedophile and rapist Christian B was named by German police last year as the prime suspect for her abduction and murder. But a source close to the case told The Portugal News ‘I’m not sure they have the right man, nor obviously are they’ (the Met). However, Christian B is yet to be quizzed over Madeleine's disappearance and says that he is innocent. It is claimed that dramatic new clues have come to light recently.
