There are some elements of Spanish Nationalism in PP; e.g. big national flag in Colon, Madrid (ok, it is a flag, nothing nationalist, BUT it is a falg with enormous dimmensions (300 sq. meters), there are Spanish flags all around in Com. Madrid (I know the place because I live there) in many roundabouts, and Castille and Leon, there are more aspects, unionism, centralism, monarchism, support og traditional but not modern tradition of tauromaquy etc. I know that´s not a nationalism itself, but if you consider the rest of parties and the history of Spain, you can see that there is in fact some Spanish Nationalism in PP, which I think might be included in the description of the ideology of the party.
