Brazil's president proposes major political reforms

Brazil's President Dilma Rousseff has proposed a referendum on political reform, following nationwide protests.

Ms Rousseff also pledged to invest 50 billion reais ($25bn, £16bn) in public transport, one of the protesters' main grievances.

More than one million Brazilians have taken to the streets to protest against rising costs, government corruption and the expense of the 2014 World Cup.
