Media captionBrazil's President Dilma Rousseff told Wyre Davies the impeachment process is "illegal"
Brazil's beleaguered President Dilma Rousseff has told the BBC she is an "innocent victim" and she will fight on as possible impeachment looms.
She vowed to "keep fighting... to come back to government if the impeachment request is accepted".
Ms Rousseff is accused of manipulating government accounts, which she denies.
The Senate will decide whether to start an impeachment trial next week. If that happens she will be suspended from office for 180 days.
Recent polls conducted by Brazil's major newspapers suggest that a majority of the 81 senators will vote in favour of the trial.
