Brazil's final presidential election debate before vote

The final presidential election debate has taken place in Brazil ahead of Sunday's vote after what has been a tight and tiring campaign.

Incumbent President Dilma Rousseff from the Workers Party is standing for a second term in office - and the latest opinion polls point to her strengthening her support.

However, with a weakening economy and rising crime, she has been pushed close in recent weeks by former environmental campaigner Marina Silva.
