Documentary makers claim to have found a 'major breakthrough' in the case of Madeleine McCann's disappearance.
Creators of the Australian TV show have said they are set to reveal new evidence in a 'landmark' television event this weekend.
Sunday Night is a current affairs show Down Under and, in a teaser clip, it has promised to reveal the fresh lead in a TV first, which filmmakers think could bring the case closer to a conclusion.

The documentary also features interviews with former lead investigator Goncalo Amaral. Amaral has been involved in several legal battles with the McCanns in the past few years.
In his book, The Truth of the Lie, Amaral claims that Maddie died in the holiday flat and Gerry and Kate covered it up. The McCanns took him to court in Lisbon to sue for libel and were awarded €500,000 (£429,000) in compensation. However, last year, an appeals court overturned that ruling.
The McCanns put in a counter-appeal, which they lost in January this year.
The filmmakers also interview Pat Brown, a US criminal profiler, who has previously said she believes Maddie is dead and her body is most likely in a 'desolate location' and will never be found.
Understandably, Madeleine's parents, Kate and Gerry McCann, have urged the documentary makers to pass any leads or new information onto the police.
A spokesperson for the family told the Daily Star: "If the Australian TV show contains any credible, fresh lines of inquiry they should, of course, have been given immediately to the police."
The show will broadcast as it leads up to the 10th anniversary of the little girl's disappearance. Madeleine was three years old when she vanished from the hotel apartment she was staying in in Praia da Luz, Portugal, while her parents were at a tapas bar nearby.
Kate and Gerry have always said they believe their daughter is still alive.
Last month, Operation Grange was given £85,000 of Home Office funding to extend its investigations until September.
