Madeleine was alive and it was
investigating 38 "persons of interest"
after reviewing the evidence.
Madeleine's parents, Gerry and Kate
McCann, said the shift from review to
investigation was "a big step forward".
Madeleine was almost four when she
disappeared in Portugal in May 2007.
She went missing from her family's
holiday flat in the Algarve resort of Praia
da Luz, as her parents dined out with
friends at a nearby restaurant.
Portuguese authorities dropped their
investigation into her disappearance in
2008, but Scotland Yard started a review
in May 2011, after Prime Minister David
Cameron had responded to a plea from
the McCanns, of Rothley, Leicestershire.
Det Ch Insp Andy Redwood, who is
heading what has been called Operation
Grange, said: "The review has given us
new thinking, new theories, new
evidence and new witnesses."
His 37-strong police team is two-thirds
of the way through examining 30,500
documents from files held by the
Portuguese, private investigators and
British police. Some fresh interviews
have also taken place.
"Over the last two years what the review
has told me is that there is no clear,
definitive proof that Madeleine McCann
is dead," Det Ch Insp Redwood said.
"So on that basis, I still genuinely believe
that there is a possibility that she is
He added: "It is a positive step in our
hunt for Madeleine that our
understanding of the evidence has
enabled us to shift from review to
Scotland Yard's decision to formally open
its own investigation - which, like the
review, will be funded by the Home
Office - follows extensive discussions
with UK prosecutors and the Portuguese.
BBC home affairs correspondent Danny
Shaw said: "It's highly unusual -
although not unprecedented - for a
British police force to launch its own
inquiry into an incident abroad."
In a statement, the McCanns said: "Kate
and Gerry warmly welcome the shift in
the Met's emphasis from review to

The Met has asked for a small number of
its officers to be present in Portugal for
the inquiries there.
As part of the review, a computer-
generated image of how Madeleine might
have looked at the age of nine was
created with the help of her family. They
marked her 10th birthday on 12 May.
By May 2012 - one year into the review -
the Home Office's costs had reached
£1.9m. The Met Police said a more up-
to-date figure for the cost of the review
would be released in due course.
The former head of the National Police
Improvement Agency Peter Neyroud said
it was a difficult investigation because it
involved two countries, possibly more.
"It was always going to be an expensive
inquiry and it is a fine judgement as to
how far you go on but if, as appears,
there are fresh lines of inquiry and a
case worth pursuing, there is a young
lady out there who deserves to be
reunited with her parents - or a murder
case that deserves to be pursued."
