What to make of the Home Office leak?

John Springford of the Centre for European Reform, a think-tank, disagrees. “This document is a demand for derogation from free movement law,” he says. “It demands that EU citizens register, while UK citizens do not have to do so, violating non-discrimination rules.” He adds: “EU leaders were clear in the negotiating mandate that they gave to the commission that, should a prolongation of the acquis be required, then all rules and institutions and the entirety of single market and EU law would have to apply. The EU has no interest in negotiating a bespoke transition.”
