Last october, we had regional elections and the world press came to Antwerp because of the expected rise of the extreme right party Vlaams Belang (expected to get more than 50%)....

It didn't happen.
Patrick Janssens, the current burgmeister was reconducted with more votes for his party (the socialists) than when he became burgmeister.

Antwerp has immigrants from more than 100 countries and it allowed them to vote.
Why the socialists success ? Because Antwerp has been well managed; there are lots of renovation works, the population is invited to participate in discussions about what happens to their street.
The immigrants saved democracy, was written in an newspaper.
