Brazil’s top electoral authority said on Tuesday that it would re-open an investigation into alleged misuse of funds during President Dilma Rousseff’s re-election campaign.

The Supreme Electoral Court will try to determine if Ms Rousseff’s and Vice-President Michel Temer’s campaign drew on donations from illegal sources.

The probe was requested by the opposition PSDB party.

It comes at a time when Ms Rousseff’s approval rating is at a record low.

If it were to uncover irregularities, the court could invalidate Ms Rousseff’s and Mr Temer’s election and trigger fresh polls.
