The former head, who spent 40 years working in the border system, called it “completely broken.” The weight of those words lies not in the criticism, but in who said them. When someone who once oversaw the border speaks out against the system, it shows the problem is no longer a policy disagreement—the situation has become unmanageable at the implementation level. The impact on markets is indirect, but the direction is clear: immigration and border issues will continue to dominate UK political headlines, and expectations for public finances and labor supply will have to adjust accordingly.
