The UK’s Serious Fraud Office (SFO) has begun investigations into Rolls-Royce’s operations in Nigeria, following accusations that the London Stock Exchange-listed engineering group filtered payments through intermediaries such as Unaoil to win deals in Indonesia, China, India and Brazil. As with previous investigations, the deals under scrutiny were transacted by Rolls-Royce’s previous management, headed by Sir John Rose. The Times newspaper reported on 20 May that the Nigerian deals involved Rolls-Royce’s alleged use of an intermediary company, PSL Engineering and Control, to influence the sale of gas turbines.
