Detectives searching for Madeleine McCann are to ask for more funds to extend their multi-million pound search, it has been reported.

Police hunting for the toddler have spent more than £11 million on a six-year investigation after she vanished during a family holiday in Praia da Luz in Portugal in May 2007. 

The three-year-old disappeared from the family's holiday apartment and has not been seen since. 

Funding for 'Operation Garage' will cease in September as police follow a final lead, however Metropolitan Police look set to request for more money to continue their investigations, reports Sky News

Scotland Yard said: "Funding is in place until the end of September. Any details about future funding will be released when appropriate."

In 2011, four years after her disappearance, then Prime Minister David Cameron arranged for Scotland Yard to investigate the case with special Home Office funding after an appeal from Gerry and Kate McCann. 

In April this year, Assistant Commissioner Mark Rowley said dectectives were still following a critical lead.
