Scotland Yard has requested a further six months’ worth of funding to continue their investigation into the disappearance of Madeleine McCann.
Police have put in the request to the Home Office to support their joint operation with Portuguese forces.
Investigations have been running since three-year-old Madeleine vanished in 2007 from her parents’ holiday apartment in Praia da Luz.
UK detectives were granted an extra £150,000 in March to continue the probe, to cover until the end of September.
Earlier this week it was reported that the search could be shelved within three weeks after running out of funding.
But the Met has asked Sajid Javid to continue to pay for Operation Grange, which was launched in 2013 after a Portuguese inquiry failed to make any progress, and has cost a total of £11.6million.

British officers have so far gone through 40,000 documents produced by Portuguese police in the original investigation, as well as information from eight teams of private investigators.
About 600 “persons of interest” have been examined and several reported sightings of Madeleine all over the world have been assessed.
