Eight years ago, in 2007, 3-year-old Maddie disappeared from her family's holiday apartment in Portugal's Praia da Luz.
Since then her parents, Gerry and Kate McCann, have fought tirelessly to find Maddie, who would now be 12.
But, despite the million pound search operation, no arrests have been made, prompting calls for the case to be shut down.
Chairman of the Met Police Federation John Tully recently spoke out, saying: “It’s time to re-focus on what we need to do to keep London safe.
"We no longer have the resources to conduct specialist inquiries all over the world which have nothing to do with London."
However, Madeleine's parents have urged the public to continue the search for their daughter.
Kate and Gerry McCann continue to pump thousands into a special fund for use when the official investigation, codenamed Operation Grange and launched more than four years ago, ends.[

Family spokesperson Clarence Mitchell said: “They realise it cannot go on forever.”
He added: “Kate and Gerry remain incredibly grateful to the Met Police for their continuing work and effort and are grateful to everyone who continues to make Operation Grange possible.
“The Government and police make the decision about funding, it is not Kate and Gerry’s role.”
