Rolls Royce has their own investigations have identified "matters of concern in these, and other overseas markets".
The company added that "it is too early to predict the outcomes, but these could include the prosecution of individuals and of the company. We will cooperate fully."
“I want to make it crystal clear that neither I nor the Board will tolerate improper business conduct of any sort and will take all necessary action to ensure compliance. This is a company with exceptional prospects and I will not accept any behaviour that undermines its future success”.
