Mr. Stephen Kent:

The review is there and we have to make sure we balance the risk assessment between safety and representations for people to maintain their jobs. We have to continue to make sure that we prioritise safety. The research we have up to now is all pointing to the fact that there is much more risk for the scheme, passengers, customers and drivers as the thing is extended. In the face of the compelling research we have at the moment, we would need new research that points us in a different direction. Otherwise, it is very hard to change position. We would be knowingly taking on much more risk and then we would all rue the day. From that point of view, we recognise that it is part of the programme for Government to undertake independent research and we will of course participate in that process.
