The parents of Madeleine McCann have set aside almost £750,000 to fund a private search if police stop looking for their missing daughter.
The Find Madeleine Fund consists chiefly of donations and profits from mother Kate's book on the child's disappearance in Portugal.
The 49-year-old has made £793,516 from the bestselling Madeleine: Our daughter's disappearance and the continuing search for her.
But nearly £65,000 was set aside for expenses and an unsuccessful libel battle against the Portuguese ex-detective who accused her and father Gerry, also 49, of accidentally killing their child and hiding her body, Mirror Online reports.
Detectives investigating the disappearance of Madeleine McCann have applied for more funding for the search.
The Home Office confirmed that it is considering an application from the Metropolitan Police for more money to keep the probe, called Operation Grange, going.
A spokeswoman said: 'The Home Office has provided funding to the Metropolitan Police for Operation Grange and the resources required are reviewed regularly with careful consideration given before any new funding is allocated.'
Government funding for the investigation has been agreed every six months, with £154,000 being granted from October last year until the end of March.
More than £11 million has been spent so far on the probe to find the missing girl, who vanished from the family's holiday apartment in Praia da Luz in Portugal in May 2007, aged three.
The size of the extra cash award raised hopes police were closing in on identifying whoever abducted the three-year-old but also led to questions about what the money would be spent on, as only four officers remain on the case.
It's been over 10 years since the disappearance of Madeleine McCann - who went missing from the resort Praia da Luz in Portugal back in 2007- and yet it still remains one of the biggest mysteries of recent times.
But one criminalist has said that he has 'no doubt' that Kate and Gerry McCann's daughter died in the apartment.
Speaking to Portuguese website Flash!, Moita Flores - who was once involved with the Judiciary Police that conducted the initial search - said: "It was impossible to pass in that window with a child, Maddie died in that house."
He added: "The secret is in that group of people and in the parents who are influential people in the British government."
Flores is a Portuguese crime expert, researcher and writer, whose beliefs also mirror those of police chief Goncalo Amaral, the Daily Mail reports.
Flores continued: "With the 96,000 euros made available by the British government, they did a reconstitution in Praia da Luz, which is the only way to solve the case."
This year is the eleventh anniversary of the disappearance of little Madeleine McCann, It is still unclear what really happened then. The guesses range from kidnapping the girl, kidnapping, murder, to her own parents, who might have done something to little Maddie.
Criminal expert Moita Flores, 65, who was also involved in the investigation, voiced his suspicions against the Portuguese website Flash! And explained his sad theory.
"Maddie has died in this apartment, I have no doubt," he says, referring to the room of the resort from which the girl disappeared. "It would be absolutely impossible to get out of this window with a child." A thesis that according to Dailymail has not yet been confirmed otherwise and should be especially for Maddie's parents like a stab in the heart.
"Until there is no evidence, her parents believe that her daughter is still alive," a spokesman said on the news page. Obtaining these would be damned expensive.
You have to make a reconstruction of the disappearance in the resort, so Moita Flores. Otherwise, the case could not be solved. But this effort would devour another 85,000 pounds (97,000 euros).
