Madeleine McCann: Parents refuse to participate in new Netflix documentary series

The parents of Madeleine McCann have repeatedly refused to be interviewed for a new Netflix documentary series revisiting the case of their daughter's disappearance 12 years ago.

The new show, which will premiere on the streaming platform later in March, follows the mystery of Madeleine from the moment she went missing from her parents' hotel room in Portugal in May 2007.

It was produced by Pulse Films over 18 months, and Netflix promises it will feature "riveting" new interviews with investigators closest to the case.

But despite repeated attempts by the series creators to get Gerry, Kate and other close friends of theirs involved, they were shut down, The Daily Mail reports.

"We would have welcomed the opportunity of working with the McCanns directly but they informed us they couldn't and wouldn't consider taking part while a police investigation is into their daughter's abduction is ongoing."

Clarence Mitchell, who is close to the family, also told the series creators that he and many of their other friends "want nothing to do with it".

The investigation into Madeleine's disappearance, dubbed 'Operation Grange', has cost more than £11 million (NZ$20.6 million) so far.
