No, I will carry on.
The important point is that we need a system that is not only fair to the people of Scotland but, as the hon. Member for Warrington South (David Mowat) said, fair to the people of the United Kingdom. We cannot have the devolution in Scotland that the Bill proposes without it affecting my constituents in North Durham and the constituents of many other Members.
Devolution raises many practical issues. One example is air passenger duty. Newcastle airport is a great example of the local council, five local authorities and the private sector working together to ensure for the region a vibrant airport with international links. It employs 3,500 people directly, with a further 8,000 people employed in the region.
