My Lords, I thank all noble Lords for their contributions.
I want to pick up on the point made by the noble Lord, Lord Smith, in response to the noble Lord, Lord Shipley. There is accountability, and that accountability is very much to the stakeholders that make up the particular STB. As for the limits or extension of these areas, that will very much be dependent on the local authorities themselves and the collaboration that takes place. The key point I emphasise is one of strategic decision-making, which is the intention behind the creation of such bodies, as we are already seeing with the creation of TfN. Indeed, the reason behind putting TfN on a statutory footing is that the very bodies that make it up have also requested this.
I will now pick up some of the questions raised by noble Lords. The noble Lord, Lord Shipley, also asked about annual reporting. The legislation makes it clear that STBs shall produce and publish their strategy and updates to that strategy. That can be seen with TfN, which produced its additional reports in March 2015 and has plans for annual updates, the next being in March 2016.
The noble Lord, Lord Beecham, asked about the extent to which different modes of transport are covered by STBs. The whole essence of sub-national transport bodies will be to cater for all modes of transport within a defined geography, including ports and airports. This can already be seen in the work of TfN, which has set out quite clearly its plans for all modes of transport, including ports and airports. I take on board totally the point the noble Lord made that this is not just about linking up rail and roads; it is about ensuring that, where there are ports and airports, these also form part of the strategic transport strategy for a given geographical region.
The noble Lord, Lord Beecham, also asked about the size of STBs. As I have already said, it is really up to the local areas to come forward with proposals; it is about bringing together local authorities. There may be some traditionally defined areas, but it is about how local authorities can come together and collaborate across traditional borders to ensure the best result for a particular region. In terms of the requirements, there must be two appropriate authorities to form an STB.
