Brazilian President Jair Bolsonaro is challenging the results of last months elections which he lost to rival Luiz Inácio Lula da Silva.

In a complaint filed with electoral authorities, Mr Bolsonaro alleges that votes from some voting machines should be “invalidated.”

The court challenge is widely expected to fail, as Lula’s victory has been ratified by the Superior Electoral Court (TSE) and acknowledged by Brazil’s leading politicians and international allies.

Mr Bolsonaro’s team now has 24 hours to present its full audit for both rounds of last month’s vote or have the court will automatically reject the case.

Bolsonaro, has for years claimed that the country’s electronic voting system is open to fraud, without providing evidence to back his allegations.

Following news of the electoral complaint, Brazil’s currency deepened losses, losing 1.5% against the U.S. dollar in afternoon trading.

The real was already suffering from investor concerns about Lula’s spending plans and economic policymakers.
