So you haven't found anything to substantiate that?
I had a look as well.
Setting aside blog entries from his fan club, about all I can find is from Portugal News:
Ex-Maddie cop runs for mayor
in News · 17-01-2009 00:00:00 · 0 Comments
Gonçalo Amaralo, former detective in the Madeleine McCann disappearance case and author of the controversial book ‘Maddie: The Truth about the Lie’ has confirmed he is set to run for Mayor of Olhão, representing social-democratic party PSD/Algarve.
(...)
Better known for his roles in the ‘Madeline McCann’ and ‘Joana’ cases – two children, one British, one Portuguese, both of whom disappeared in separate incidents in the Algarve – ex-police officer Gonçalo Amaralo said his most recent challenge is the “result of my availability and an invitation that was made by PSD/Algarve and the local municipality”.
(...)
Tavira Mayor of twelve years Macário Correia has voiced his approval of Sr. Amaral’s nomination, considering it “positive”, that the PSD party has found a candidate that has “a strong civic participation and who has fought for justice”.
Hmmm.
I'd never heard of this chap, but I found this:
O Supremo Tribunal Administrativo determinou "a perda do actual mandato" de Macário Correira, presidente da Câmara de Faro, por violação do Plano Regional do Ordenamento do Território do Algarve e Plano Diretor Municipal em 2006.

It seems that he's another one whose found himself in a bit of legal bother... and he's not even the deputy mayor who literally munched up documents during a police raid.
Never a dull moment down there...
Part of the problem we have is that we have access only to translations we are given, few of us speak, read or write Portuguese ... with the result that the information we have to hand is filtered and we see those parts we are allowed to see and those parts which are spun for one individual and against others.
I think Portugal is no longer going to tolerate corruption at any level and have been proactive for the past few years in rooting out the dinosaurs.
I think Mr Amaral's time has come and gone in Portugal where it really matters to him ... perhaps tomorrow will find us one step further forward in the saga and we may be able to judge where it all goes from here.
