Well, in relation to coal-tip safety, first of all, that is the sum of money we asked for in the comprehensive spending review. It's a three-year sum of money, and it is matched by money that the Welsh Government is providing, and it will mean £220 million altogether, over [correction: by the end of] that three-year period. And we are satisfied that that is the amount of money that the system can absorb, because financial resources are only one aspect of what has to be lined up in order to do that sometimes quite challenging and complicated work, given the nature of the topography that we are talking about. But we are confident that that amount of money will allow us to press ahead with a significant programme of work, focused on category D tips particularly, where the safety considerations are greatest, and also talking with my Cabinet colleagues about how that investment can also create new economic opportunities in those places. So, it is primarily safety from the Welsh Government's point of view, but it is also part of our ambitions to stimulate economic activity in those places.
Of the £455 million [correction: £445 million], only £48 million of it actually comes into the Welsh Government's budget, the rest of it is essentially money that Network Rail will be deciding upon. The £48 million is £12 million for each of four years. So, you will see that in next year's budget. Could we have used more? I think we could. So, we will continue to press the case for further investment in core Valleys lines enhancement. That's what this money is for. We already have money from the UK Government to enable us to carry out maintenance, operations and renewals, and that was in the previous budget. The £12 million annually that comes in this year's budget is for enhancements. There are a series of things that we would like to do in the core Valleys lines: reopening the Aberdare-Hirwaun link, for example. The £12 million won't allow us to do everything that we had hoped to do, but it will allow us to do some things that we couldn't do without the £12 million.
