Scotland Yard will continue its search for missing Madeleine McCann.
The commitment comes despite German authorities believing she was murdered.
Metropolitan Police Commissioner Dame Cressida Dick said the Yard is working “really, really closely” with the German authorities.
However, she did not expect them to share all their evidence.
German prosecutor Hans Christian Wolters says he has “concrete evidence” that Madeleine was killed by convicted rapist and paedophile Christian Brueckner, 43.
Investigators believe the three-year-old was taken from her Portuguese holiday apartment in Praia da Luz in May 2007.
Dame Cressida said:
“We’re continuing to work very closely with our colleagues in the BKA (Germany’s Federal Criminal Police Office) in Germany, as you know, and the PJ (Polícia Judiciaria) in Portugal.
“We do have our small team still working on that and there’s no significant change for us in terms of our resourcing or posture.
“As you know, we have some funding to continue that and we are continuing it.
“We will continue until the time that it is right, either because much more light has been thrown on this and, or somebody has been brought to justice.
“Or, if we feel we have exhausted all possible opportunities.
“We’re not any of those stages at the moment, and the team continues.”
“So, we’re working really closely with the German authorities. I would not expect necessarily every single piece of material to be shared with us. I’m sure they’re sharing the relevant things at the relevant times with us.
“We are working really, really closely with them.”
