The President of Brazil Michel Temer was accused of taking a large bribe by former President Dilma Rousseff. The accusation follows Rousseff's removal from office in September 2016.
Rousseff, who took office in 2011, has accused Temer of accepting a payment of one million reals ($297,150).
The payment is alleged to have been made by Otavio Azevedo, the former head of construction firm Andrade Gutierrez. Azevedo testified that the payment was made to Rousseff as a bribe.
But the documents Rousseff's lawyers filed allegedly show that Andrade Gutierrez transferred the cash directly to the general campaign finance fund of Brazilian Democratic Movement Party (PMDB). Temer is member of PMDB.
A cheque for the same sum was then allegedly paid into Temer's personal campaign fund. Rousseff's lawyers say that Mr Azevedo lied and that the bribe went to Mr Temer, who should therefore be impeached.
Temer has stated that Ms Rousseff was head of the ticket and held all responsibility for any wrongdoing. His party said the donation was legal and was declared before the electoral court.
Rousseff was ousted by Brazil's Senate in September after she was accused of manipulating the budget. Temer had been her vice-president prior to her impeachment and was promoted to see out the final years of Rousseff's term, until January 2019.
At the time of her impeachment, Rousseff claimed she had been the victim of a political coup and promised she would appeal the decision.
