You ask why Anne?
The Portuguese are a very proud people, the GNR and especially the PJ will be extremely resentful at having to play second fiddle to a foreign police force on their patch...a fact of life unfortunately.
The damage done to tourism on the Algarve by the McCann case was widespread. What really astounds me is the timing of this announcement by the Met which couldn't have come at a worst time for Portugal given the imminent tourist season.
I don't agree, John. I've lived in Portugal for 33 years and I had no preparation at all to their mentality, having a Calvinist education, though the spirit which animated the great discoveries wasn't unfamiliar to me. Raul Ruiz once called the Portuguese "the athletes of the low profile", and this is very right. They're proud, yes and luckily, but they'll accept (the fatum) whatever SY will discover if and only if the AG's conclusion isn't just thrown to the garbage bin : no evidence of the crime that resulted in the disappearance of Madeleine McCann has been found.
On the tourist topic, serious sociological studies deny any relation between the diminution of mass tourism and the McCann case. The global tendency is towards residence tourism, people (like the Smith family) having a double residence. If you wish, I have a good link (in French).
