Bolivians go to the polls on Sunday for presidential elections that polls suggest will favour the incumbent, Socialist leader Evo Morales.

His opponents accuse him of violating the constitution, which forbids anyone running for a third consecutive term, but amid the controversy there is one issue that binds all Bolivians and which Morales is using to his advantage: a 135-year-old territorial dispute with its neighbour Chile.
