From the BBC:
Brazil's Social Security Minister, Carlos Lupi, has resigned nine days after police unveiled a major corruption scandal which defrauded pensioners of $1.1bn (£829m).
Federal police allege that over the past decade, the National Social Security Institute (INSS) made unauthorised deductions from payments made to millions of pensioners.
The money was allegedly paid to several associations and unions, which then shared the earnings with corrupt government officials.
Lupi has always denied any wrongdoing and said he ordered an investigation as soon as he heard about the allegations. …
