They did a review of the case. They started at the beginning. They used the Portuguese statements so as they said there was no need to repeat these. They ruled the McCann's out.
Even though Colin Sutton says he would have questioned the McCann's his conclusion was that Madeleine was abducted.
The German Police say Madeleine was abducted, I didn't see any interference by the British Police for them to come to their conclusion.
The claim made that the MET was confined to one avenue of investigation is
- idiotic on the part of those who actually believe or more likely, purport to believe it
- insulting to those professionals tasked with investigating if there were any more leads to be followed which either had not been followed, or which had developed during investigation by the McCann detectives
Nobody in their right minds would recommend initiating any sort of investigative procedure without first of all investigating everything piece of minutiae which had gone before.
This includes the 'evidence' which did not stand up against constituting Murat and Kate and Gerry McCann as arguidos; in the latter case the false dog indications which form the cornerstone of the sceptic belief system.
