My right hon. Friend raises a crucial point. Business confidence is important, but so is the confidence of those who work in the North sea, following the recent dreadful, high-profile tragedy that claimed so many lives. That is why there is again consideration of the reintroduction of personal locator beacons. However, in the past, those lights interfered with the long-range beacons fitted to helicopters and life rafts. Of course we are looking into the detail of that horrific crash, and are seeing what lessons can be learned. The reintroduction of those beacons is now under consideration.
