The search has cost £11,600,000 so far and the funding was due to run out in September this year.
A Metropolitan Police spokesman said at the time that the force was in ‘dialogue regarding further funding’ with the Home Office, which has now been granted according to Sky News sources.
A Home Office spokesperson said they were maintaining an ‘ongoing dialogue with the MPS,’ today.
Maddie, from Leicester, was three years old when she disappeared in May 2007 while on holiday with her parents in Praia da Luz, a resort in the Algarge region of Portugal.
Scotland Yard launched its own investigation, Operation Grange, in 2011 after a Portuguese inquiry failed to make any headway.
UK detectives were granted an extra £150,000 in March this year to continue the probe, until the end of September.
The Home Office said at the time that any requests for further funding by the Met Police would be ‘carefully considered.’
The new funding is expected to last until the end of March 2019.
A spokesperson for Maddie’s parents Kate and Gerry McCann said in September: ‘They remain incredibly grateful to the police. They hope the Scotland Yard investigation continues and that more funding is granted.’
There has not been any significant clues to what happened to Maddie.
No arrests have ever been made in the case.
