One thing that my constituents in Dover and Deal were absolutely clear about when they decided to vote by a large majority to leave the European Union was the need to take back control of our borders and to end uncontrolled EU immigration-to end free movement. It is not just in my constituency; it is regions across the country, including Labour leave areas, which I know feel the same way. It should therefore be a red line for this House to ensure that, whatever happens, free movement comes to an end, because our constituents up and down the land have been very clear about that. We must also ensure that we take the full opportunities that leaving the European Union will afford this country. That is why we need to leave the customs union and why we cannot stay in the EEA. The truth is that 90% of future economic growth in this world of ours will come from outside the European Union. In recent decades, the share of global GDP represented by Europe has halved, from about a third to just about 15%. Europe is in relative decline. We do not have to go that way ourselves. We can jump forward to explore, trade and participate in the fast-growing areas of the planet. I am not saying that it will be easy, but it is an instruction that has been given to us by our constituents and by this nation. What is more, when it comes to trade in goods, it is important to remember that the European Union sells us £100 billion more goods than we sell to it. It is therefore in its interests to ensure that there is frictionless trade, more so than it is in our interests. We need to ensure that we are fully prepared for every eventuality and every single kind of deal that we might do. That is why I am making the case that we need to modernise our systems. We have needed to modernise them for years, so it is no-regrets spending. We should modernise them because the border is no longer as it was in the 1950s, where we checked every lorry; the border is a tax point. With the systems in place that technology now enables, trusted traders could be required to account for their loads and we could ensure that there was no need for any checks at the border whatsoever. That includes Northern Ireland. Those who are opposed to us leaving the European Union like to cite Northern Ireland, but the truth is that we do not need any infrastructure or any checks at the border. We can have frictionless trade through the border, with audits in workplaces and computer systems that ensure there are proper audits. Singapore has such a single-window system in place, and countries around the world have such systems. We need to take advantage of that, because that is the kind of future we can make, and that is why I have been making the case for that investment to be made.
