BRASILIA (Reuters) - Brazil's opposition parties on Thursday filed a request in Congress to impeach President Dilma Rousseff for breaking fiscal rules by allegedly manipulating government finances to benefit her re-election last year.

The request was backed by some members of Rousseff's main political ally, the fractious PMDB party, Brazil's largest, whose votes would be needed to succeed in ousting the president.
