In your opinion ... or even better if you have a cite to substantiate what you are posting ... should Madeleine's case be taken to the stage where it can go no further ... under whose jurisdiction will any new evidence coming be assessed, who will the someone be who will assess it, file it, etc. as part of day to day tasks, with the cost being met from existing budgets.
Whose budget will meet those costs?
That's a very interesting question. The official line is that Operation Grange are assisting the Portuguese with the investigation into the disappearance of Madeleine McCann.
Whether that means that they have shared or will share all the evidence they have amassed with the Portuguese isn't known.
We will know if the case is re-archived in Portugal, but we won't necessarily be told by our secretive authorities what it's status is in the UK.
If funding of the case in the UK ceases then someone will no doubt make a decision about any new evidence arising.
