Election due: Elections for a new president and parliament are expected on October 5.
Backdrop: Brazil, the biggest economy in Latin America, faces an uncertain election year. Its stock market, down almost seven percent so far this year, has been battered by Federal Reserve tapering fears. A severe drought is stretching the country's finances, the central bank has hiked interest rates by 350 basis points since April last year to contain inflation and last year a small demonstration against a 50-cent rise in bus fares exploded into the biggest street protest Brazil has witnessed in years.
Last week Standard & Poor's (S&P) downgraded Brazil's long-term debt rating to BBB minus, one notch above "junk" status.
Key election themes: Poor public services, rising living costs and deteriorating public finances and corruption.

Expected outcome: President Dilma Rousseff from the Workers' Party is running for re-election and despite the weak economic backdrop she is the favorite to win. The outcome however, could still be a close call, analysts say. Other candidates include Marina Silva, an environmentalist and former environment minister.
The wild card: The World Cup. What exactly does soccer have to do with an election? Well, potentially a great deal if shutdowns associated with preparing or hosting the sporting event takes a toll on the economy, analysts say. A law passed last year gives the 12 cities hosting matches and the states in which they are located the right to declare special holidays on game days, Reuters reported. While it's not yet clear whether these holidays will go ahead, the impact is certainly something to watch.
View from the experts: "The poorer have tended to be loyal supporters of [former President Luiz Inacio Lula da Silva] Lula/Dilma, since the government's social programs benefited them," said Guy Burton, assistant professor, School of Politics, History and International Relations, University of Nottingham, Malaysia. " It's also the case that the support of the Workers Party has shifted over the last decade, from its core base in the industrial urban heartland and trade union movement of the south, including Sao Paulo to the poorer, rural, less educated and marginal Northeast."
