Can I thank David Rowlands for his questions, and say that I'd very much welcome a cross-party debate on the level of investment from the UK Government in rail infrastructure in recent times? I think that would assist in strengthening our hand at the negotiating table, and ensure that Network Rail and the UK Government recognise that there is demand across all parties in the National Assembly for Wales for fairer funding when it concerns rail transport in Wales. 

In terms of HS2, yes, there is the potential for HS2 to have an adverse impact on the economy of south Wales, and that's why we're arguing that we need to see investment in the south Wales main line come as soon as possible, to ensure that south Wales, and, indeed, this applies to the south-west of England, remain competitive and go on being competitive on a UK and global stage. In north Wales and, potentially, in mid Wales, HS2 offers the opportunity for those regional economies to be significantly strengthened and boosted, but it will require the right outcome, specifically with regard to the Crewe hub, ensuring that there's the right outcome, the right infrastructure in place to the north of Crewe station.

In terms of HS2 as a whole, what I would say is that—and this goes for the regions within Wales as well—what we should not do is argue that we should hold back the prosperity of one region in order to maintain current levels of prosperity for another, whereas actually what we should be arguing for is enhancements across all regions. That's why, again, I clearly state that HS2, whilst it could have an adverse impact on south Wales, if we get the right level of investment into south Wales and the main line into and from south Wales, then the adverse impact could be mitigated. So, my consultation response to the Secretary of State concerning the Great Western Railway franchise clearly stated the need to ensure that there were mitigating proposals that could be adopted that would then guarantee current levels of prosperity for south Wales and ensure that the south Wales economy can prosper in the future. 

In terms of the business cases, the commitment for taking forward business cases rests with the UK Government, but we need to ensure that there are irresistible cases put forward to UK Government. I outlined in my statement how there is significant spend taking place elsewhere in the UK. What I don't want to see happen is for us to just rely on business cases designed elsewhere. What I wish to see happen is for us to influence those cases at the earliest opportunity, and that's why we have experts and that's why we have Transport for Wales working on those cases right now.
