Can I thank the Member for his question, and just remind Members again that this huge undertaking will open up the Heads of the Valleys for further economic development and prosperity? It's our intention, first of all, to minimise exposure to the Welsh Government and therefore to taxpayers as a consequence of the excessive costs, but once the level of Welsh Government's liability has been confirmed, decisions will then be made on how best to fund any shortfall, recognising what the opportunity costs of this increase will be. Future budget profiles will reflect these increases so that the impact can be considered as part of the ongoing delivery of the national transport finance plan.
