Police in Brazil’s capital are on stand by for protests as the country await the outcome of a congressional committee vote.
The vote is a key step in the process to impeach President Dilma Rousseff.
The 65-member committee will decide whether to recommend impeachment over allegations she manipulated government accounts to hide a growing deficit.
If Rousseff, who strongly denies the allegations against her, can get 172 members to oppose the impeachment, the proceedings will be shelved.
If, however, 342 vote in favour of the impeachment, the matter will go to the Senate.
The Senate will then have to decide whether to proceed with the impeachment.
If that happens, Rousseff will be suspended for 180 days while the impeachment trial continues in the Senate.
For her to be removed from office permanently, two-thirds of the Senate will have to vote in favour.
