In pictures: Leaving Bolivia

Alicia comes running to take a call from her uncle, who's working as a building labourer in Madrid.

"He calls to ask how we are, and whether we need anything. We all miss him a lot," says Alicia.

"I'd like to go to Spain. The living here is not good. There is a lack of everything.

"In Spain you can live better, but it's hard for me to imagine what it must be like."
