Support for a union between Spain and Portugal (Iberian Federation) continues to increase

Readers may remember this article from 2009 on support in Spain and Portugal for a union between the two countries, where the support for a union was 30.3% in Spain and 40% in Portugal, much more than the 25% in Portugal just three years before in 2006.

It turns out that support is continuing to inch higher. Info from the article:

The number of those in Spain and Portugal in favour of an "Iberian Union" between their two countries is rising, according to the third Hispanic-Luso Barometer carried out by the University of Salamanca with the Centre of Investigation and Studies of Sociology in Lisbon.

The survey will be presented tomorrow, and shows that more in Portugal than in Spain are in favour of a union, although support for the idea continues to grow in both countries. According to the most recent barometer, 31% of those in Spain are in favour of some type of association, while 45.6% are in favour in Portugal.
