Chilean students are expected to stage another protest on Wednesday calling for education reforms in the Latin American country. Their demands are nearing the top of the political agenda just six months before general elections. But the student leader who became famous worldwide when the protests began in 2011 is now changing gears. Instead of just leading more protests, Camila Vallejo is now seeking a seat in Congress and push reforms from within the system. Al Jazeera's Lucia Newman reports from Santiago.
