More than a million Brazilians have joined anti-government rallies across the country, ramping up the pressure on embattled president Dilma Rousseff. Opponents blame Ms Rousseff for a severe recession and a corruption scandal also engulfing her predecessor, Luiz Inacio Lula da Silva. The peak of the march reached 1.4 million people in Sao Paulo, the city's state security office said. Smaller marches took place in many cities across the country.
