"This work has enabled us to better understand events in Praia da Luz the night Madeleine McCann went missing and ensure every possible measure is being taken to find out what happened to her.
"We still have very definite lines to pursue which is why we are keeping a dedicated team of officers working on the case. We have given this assurance to Madeleine's parents, Kate and Gerry McCann."The Portuguese police remain the lead investigators and our team will continue to support their inquiry. They have extended every courtesy to Operation Grange and we maintain a close working relationship. I know they remain fully committed to investigating Madeleine's disappearance with support from the Metropolitan Police.
"The Met was asked to take on this exceptional case as one of national interest. We were happy to bring our expertise to bear only on the basis that it would not detract from the policing of London; and the Home Office have additionally funded the investigation above normal grants to the Met. That will continue at the reduced level.
"I have overseen this investigation since 2012 and am very grateful for the enormous assistance of the media and public so far which, through the appeals, have generated new information and lines of Inquiry. "
Our decision and rationale has been discussed with Mr and Mrs McCann.Mr and Mrs McCann said: "We would like to thank all the staff from Operation Grange for the meticulous and painstaking work that they have carried out over the last four and a half years. The scale and difficulty of their task has never been in doubt.
"
We are reassured that the investigation to find Madeleine has been significantly progressed and the MPS has a much clearer picture of the events in Praia da Luz leading up to Madeleine's abduction in 2007.
"Given that the review phase of the investigation is essentially completed,
we fully understand the reasons why the team is being reduced."We would also like to thank the Home Office for continuing to support the investigation.
"Whilst we do not know what happened to Madeleine, we remain hopeful that she may still be found given the ongoing lines of enquiry. "
Like I said. In the loop.
