A new prosecutor in Portugal has been appointed to the case and is said to be "utterly determined" to solve it, a source close to the investigation told the Daily Mail.
The prosecutor, Ines Sequeira, described as "very ambitious" by the paper, was appointed just as Scotland Yard prepares to return to Portugal later in the month to question up to seven suspects.
The new appointment coincides with a U.K. government report estimating that $17 million has been spent so far on the investigation, according to the Daily Mirror.
Madeleine disappeared on the evening of May 3, 2007, while she was sleeping in the same room as her younger twin siblings at the Ocean Club resort in Praia da Luz in the Algarve while her parents dined with friends nearby. Her mother discovered she was missing when she returned to check on the children at about 10 p.m.
Scotland Yard's detectives are reviewing the case and have been issuing new descriptions of suspects, seeking further interviews and digging over areas of scrubland near the apartment where she went missing.
Madeleine would now be 11.
