The move shields Lula from possible prosecution by a federal judge investigating a massive corruption scandal named Operation Car Wash. 

But Ms Rousseff said that was not the motivation for the appointment.

"Lula's arrival in my government strengthens it and there are people who don't want it to be stronger."

Under Brazilian law, cabinet members can only be tried by the Supreme Court.

Lula was questioned two weeks ago over allegations of money laundering connected to Operation Car Wash.

He says the allegations are aimed at preventing him from running for president again in 2018. 

He is a "skilful political negotiator" and experienced leader who will help kick off economic recovery, said Ms Rousseff.

During his time in office, the Brazilian economy experienced unprecedented economic growth and wealth redistribution.

"I believe [former] President Lula, who was in charge of the country for eight years, cannot have his reputation destroyed in this manner," added Ms Rousseff.

Hours after the announcement, protesters gathered outside the Presidential Palace in Brasilia and in at least three other cities. 

In Congress, opposition politicians gathered around a microphone during a chaotic session and chanted "resignation".
