That may well be the case, but we are now talking about hypotheticals, so I suggest that we wait until the review has finished and
look at its conclusions in the context of the report from Allan Cook. The Government will make a decision at that time.
I turn to the comment of the noble Lord, Lord Birt, about why we do not have a long-term railway strategy. That is exactly what we are doing at the moment with the Williams rail review, which is looking at the status of the rail network and the service operators to see whether and how we can improve the system for the future.
I turn to some of the more specific points raised by noble Lords. There was a bit of discussion around investment in the north and how important it is; that was brought up by the noble Lord, Lord Wallace of Saltaire, and the noble Baroness, Lady Randerson. It is of course absolutely critical, as the Government recognise. Northern Powerhouse Rail could be transformative for the north, but probably not in isolation. It needs to be part of a larger project, which is why the Government are supporting Transport for the North to develop the options for Northern Powerhouse Rail. We committed £60 million at the spending review in 2015 and £37 million in 2018, which is on top of the £300 million we have committed to make sure that HS2 infrastructure accommodates a future Northern Powerhouse Rail and Midlands services. Therefore it is part of a bigger project, and other developments are certainly being included.
On the Oakervee review and accountability, I have already mentioned that costs, timescales and benefits will all be tied up in the review. The noble Lord, Lord Tunnicliffe, spoke about accountability and HS2. I refer him to a comment made by my colleague the Transport Secretary, who was very clear that he wanted us to be as transparent as possible. That includes on costs and schedule, which is why we published the Cook report. The noble Baroness, Lady Kramer, raised that as well. Therefore, there will be more transparency and accountability. We are not minded to introduce quarterly reporting on HS2 at the moment, as it already provides reports to Parliament, as required by the framework document, and we believe that that level is proportionate and sufficient. Of course, noble Lords may request debates on HS2 at any time.
The noble Lord, Lord Adonis, claimed that it was a bit left hand/right hand, given my opening remarks and the fact that we are having a review. However, I do not see it like that. The process for HS2 is positive, and the review we are having is a sensible reconsideration of the facts. A sensible reconsideration should never be confused for a lack of support.
A number of noble Lords mentioned whether work should continue during the Oakervee review. Certainly, the Prime Minister was very clear that the fact that we are having a review should not unnecessarily delay the progress of HS2. That would be wrong, and it would mean that costs would rise. That is why limited enabling works are being undertaken by HS2, and why your Lordships are being asked to consider phase—
