Madeleine McCann went missing almost ten years ago but the circumstances surrounding the disappearance of the little girl are still a mystery.
The three-year-old was on holiday in Praia da Luz, Portugal, with her parents, Kate and Gerry McCann, back in May 2007.
Her parents were dining at a nearby tapas restaurant with friends while Maddie was left in the holiday apartment with her two-year-old toddler siblings, Sean and Amelie.
When Kate and Gerry returned, Maddie was nowhere to be seen, and despite an investigation which now totals more than £11 million, Maddie has never been found and the case has never been solved.
But a brand new TV documentary claims to have discovered a 'major breakthrough' in the search for Maddie, who would now be 13-years-old.
The show, which is set to air in Australia on Channel 7's Sunday Night programme, describes itself as a "landmark TV event", speaking to a forensic scientist, criminologist and former lead investigator, Goncalo Amaral.
Amaral recently won a libel battle against the McCanns after they tried to sue him for alleging in both a book and a documentary that they had been complicit in their own daughter's death.
Amaral believes that a full reconstruction could help shine a light on what really happened.
A spokesperson for the McCanns requested that the people behind the documentary hand over any "credible" evidence to police.
It is believed by some that the information contained within the documentary could bring the case closer to being solved.
