The country could see its largest protest so far for the Selecao's upcoming Confederations Cup clash against Uruguay, in which Fifa president Sepp Blatter is to attendAround 100,000 people are set to take to the streets of Belo Horizonte to protest on Wednesday ahead of Brazil's Confederations Cup semi-final with Uruguay.
It is just the latest in a number of demonstrations which have filled the country's cities in recent days and, with it being a holiday in the capital of Minas Gerais, authorities are expecting the largest turnout so far.
The Public Ministry of the city had suggested the semi-final be postponed out of fears for people's safety, but the police have since guaranteed the public's welfare following the decision to draft in reinforcements from Brazil's national guard.
The march, which is being organised by the city's residents and co-ordinated via social networking platforms, is fuelled by the population's anger that the government is ignoring its country's public service issues while focusing its attentions on hosting of sporting events such as the World Cup next summer - the cost of which is believed to be a source of much of the hostility.
Wednesday's demonstration is designed to be a peaceful protest, but its organisers have spread the word through social networking sites as to what they expect people to wear, including: a long-sleeved shirt, pants, gloves, goggles and with a handkerchief covering their face.
Fifa president Sepp Blatter is expected to be in attendance for the match, though it is not known whether or not the increased security has been implemented due to his presence.
Brazil striker Fred, who is expected to start against Uruguay, revealed how he supports the protest and hopes the demonstration can pass without incident.
"I'm in favour of the protests because the people deserve better," he said. "It has to be done without violence and vandalism though.
"I'm hoping it will be peaceful tomorrow, without confrontations with the police."
