Rolls-Royce has said that it is in talks with the Serious Fraud Office over possible bribery and corruption.

"It is too early to predict the outcomes, but these could include the prosecution of individuals and of the company," the British firm said.

The aircraft engine manufacturer said it had passed on information about alleged malpractice by intermediaries.

The "intermediaries" involved are local companies that provide sales and distribution, and repair and maintenance services for Rolls-Royce in countries in which the UK firm does not have enough of its own people on the ground.
