A Catalan critic opens traditional Catalan book fest

People in Spain's Catalonia region celebrate Sant Jordi, or Saint George's Day, by giving each other books and roses. It's about language and love, but this year, there's a bit of anger thrown in. It's because the opening author, Javier Cercas, lives in Catalonia but only writes in Spanish - a no-no for local language purists. Cercas is also a critic of Catalan independence. It's brought separatists into the street, although in low numbers, as The World's Gerry Hadden reports from Barcelona.
