I understand precisely the hon. Lady’s concern. This is an important and sensitive issue, and I will be engaging on the EU track in relation to it. I will also, at the right time, make sure that I am properly versed and properly briefed on the matter, and indeed that I visit the border area to take a look for myself.
It is worth emphasising two key principles that we share with our EU friends. The first is that article 50 dictates that a withdrawal agreement must come alongside a framework for the future agreement. The second, flowing from that, is that nothing is agreed until everything is agreed. The Government respect and prize both those principles, and we will not sign away our negotiating leverage or spend taxpayers’ money in return for nothing. In December, we agreed that the financial settlement would sit alongside a framework for a deep and mutually beneficial future partnership. We agreed that we would meet our commitments as they fell due, with ever-declining payments over a finite period that will add up to a tiny fraction of what our net contribution would have been as a member. If either side should fail to meet their commitments under this overarching package—we certainly do not expect that to be the case—that would have consequences for the deal as a whole that we are striving to secure.
