Dilma Rousseff is fighting for a second term as president of Brazil, at the head of the powerful PT Workers’ Party.

Economic growth is slumped, Brazilians have been rebelling over social services… it’s the closest election in a generation.

Rousseff’s rival is Aécio Neves of the PSDB Social Democrats. He was born into privilege, and is the favourite of many liberals and conservatives.

The left have been in government for 12 years. Before that, the right governed for eight years.
