Rolls-Royce says it does not tolerate improper business

The British engineering giant, Rolls-Royce, has been accused of being involved in a huge corruption scandal centred on Brazil's state controlled oil company, Petrobras.

According to court documents supplied by a former Petrobras official, Rolls-Royce was one of several big foreign companies which paid hundreds of thousands of dollars in order to secure lucrative oil contracts.

As Wyre Davies reports from Brazil, the company has responded by saying it would not tolerate improper business conduct and would cooperate with the authorities.
