To go along with this I just received this nformation from one of our Portuguese friends on another board:
Colomom - I'll try to assess the portuguese newspapers, but it'll always be my opinion only, ok?
The most reliable of all sources would be Lusa, the central newsagency for Portugal. But they are no newspaper; they are just the main source for the media in general.
Let's start with the more 'serious' side of the scale, which would be Expresso (a weekly) and Publico (daily). They have devoted very little of their editions to the Madeleine case, and usually it's very 'dry' stuff. Circumspect & reliable.
Sol is a respectful weekly, in fact an offspring of Expresso and its closest competitor. The coverage from Sol has been more intense, but you'll have to distinguish between 'investigative' reports from Felicia Cabrita and news articles, which will cover the stuff they get from Lusa. Controversial in a well founded way.
At the center of the scale, there are dailys Diario de Noticias, Jornal de Noticias and Correio da Manha. CM is the most sold daily newspaper in Portugal. It is usually a bit 'popular' in a sense that it does cater for the 'masses', but they have built a reputation, over recent years, of having good police sources. Diario de Noticias & Jornal de Noticias belong to the same group, and they are in fact very similar. JN is mainly read in the North area of Portugal, while DN is maily read by the South. They are not very different from Correio da Manha, although they pretend to look more 'serious'. These three are the most popular papers and it shows. Exciting, but not tabloid style.
Then at the other end there is 24Horas. The closest thing that Portugal has to a tabloid - but they are mere apprentices when compared to what I've seen in the Sun, for example. Don't believe everything they print, I would advise. Saucy and mostly exaggerated.
