Aerospace company Rolls Royce is under formal investigation by Britain’s Serious Fraud Office.
The company is being probed over possible bribery and corruption in China and Indonesia.
In 2012, Rolls Royce said it had passed the SFO information relating to bribery involving intermediaries in overseas markets.
It said at the time it could face prosecution over the allegations.
The SFO had been reviewing the findings of an internal investigation, held by the company earlier this year.
