OREANDA-NEWS. February 17, 2015. Rolls-Royce said Monday it will take "all necessary action" to comply with the law after the Financial Times reported it was accused of involvement in a bribery scandal with the Brazilian energy giant Petrobras.

The British engine maker, which makes gas turbines for oil rigs for Petrobras, allegedly paid bribes via an agent in exchange for a \\$100-million contract as part of a scheme in operation over the past decade, the FT reported, citing testimony from a former Petrobras executive.

"We want to make it crystal clear that we will not tolerate improper business conduct of any sort and will take all necessary action to ensure compliance," a Rolls-Royce spokesman said.

The FT reported that former Petrobras executive Pedro Barusco told Brazilian police that he had received \\$200,000 from Rolls-Royce -- only part of the bribes he alleges were paid to politicians and other executives at the group.

Meanwhile, mounting allegations that Brazilian President Dilma Rousseff's party received hundreds of millions of dollars in a kickbacks scandal engulfing Petrobras have sent her poll ratings tumbling.

Rousseff only embarked on a second term in office last month, having succeeded popular Workers Party (PT) predecessor Luiz Inacio Lula da Silva in 2011.

Rolls-Royce is already facing a corruption probe in Britain, where the Serious Fraud Office is investigating alleged bribery linked to the group's overseas operations.

In late morning deals, Rolls-Royce shares slid 1.27 percent to 932.5 pence on London's FTSE 100 index, which was 0.12 percent lower at 6,865.47 points.
