Panorama: Five years ago, Madeleine McCann disappeared from a family holiday apartment in the Algarve, Portugal. Frustrated by Portuguese police and public opinion that viewed them with suspicion, Madeleine's parents persuaded prime minister David Cameron to order a review of the case. Is this new investigation, by a top unit of the Metropolitan Police, the last chance of discovering what happened? For the first time, the senior UK investigator tells Panorama how he is working collaboratively with Portuguese police and explains why he believes he has the best opportunity yet to help solve the mystery of Madeleine McCann.
