More than £11 million has been spent on the investigation to find the missing 3 year old child who vanished from the family’s holiday apartment in Praia da Luz in Portugal in May 2007.
Funding for the investigation is in place until the end of September but Metropolitan Police have requested more money from the Government.
A spokesperson 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.”
The family spokesman is quoted as saying: “Naturally, Kate and Gerry hope the Met request is granted.
“They are encouraged that there remains work to be done that requires extra funding and they remain very grateful to all Operation Grange officers who are continuing to look for their daughter.”
Since 2011, the Met Police have been assisting with the search for clues about what happened to Madeleine, with officers visiting the holiday resort in 2014.
Madeleine’s parents, Kate and Gerry McCann have said they will never give up hope of finding their daughter.
