I must make a few more moments of progress. We have a full debate ahead of us on the strengths of the Union.
Let me say something about the shared economy and the strong internal market which is one of our biggest strengths, and which is important for all our prosperity. The UK internal market is, of course, the vital first market of the UK. As one of the largest economies in the world, we buy and sell among our nations, and that creates wealth and jobs for every part of the UK.
As we leave the EU, we must protect the benefits of the UK domestic market. We are a world leader in financial services, defence technology, car production, food and drink, digital technology, energy, music, films and television, and all parts of the UK have their role to play in those world-leading industries. Scotland’s exports to the rest of the UK are worth four times more than those to the EU, and 56% of Northern Ireland’s external sales are to the rest of the UK. We as a Government are committed to strengthening these links between the economies of our nations. For example, between England and Wales we are abolishing the Severn Bridge tolls and investing in cross-border railway links such as the Halton Curve. Let us not forget how many people cross our internal borders every day as part of normal life. As the Prime Minister pointed out during her speech in Northern Ireland on Friday, our Union is rooted in both our history and our collective achievements, but it is our future together that is our greatest strength.
