The environmental group has written to Transport Secretary Patrick McLoughlin and Environment Secretary Liz Truss, posing four questions:
- Did the government know before this month about the existence of so-called ‘defeat devices’?
- If it did, what did it do to combat efforts by car manufacturers to fix emissions tests?
- If the government was aware of the existence of ‘defeat devices’, did it discuss the issue with manufacturers of diesel cars? If so, how many meetings took place, who attended and what was the outcome?
