Madeleine McCann was just three years old when she was taken from her bed during a family holiday in Portugal 13 years ago.
More than a decade after she disappeared from Praia da Luz on May 3, 2007, police have revealed a 43-year-old German prisoner has been identified as a suspect.
From 2007 until now millions of pounds has been poured by successive governments into a Metropolitan Police investigation.
Four months after she went missing Madeleine’s parents Kate and Gerry McCann were made suspects by Spanish police and the couple have faced a barrage of abuse ever since, despite being removed as suspects in July 2008.
A Netflix Documentary released in April 2019 only made matters worse for the pair, but the latest revelation comes as a shot in the arm.
Madeleine was taken from the holiday apartment where she was sleeping in a room with her then two-year-old twin siblings, Sean and Amelie, and the family have been searching for answers ever since.
Here, MailOnline has delved into the twists and turns of the most publicised missing person case of the 21st century.
