There are some questions around built-in safeguards in the immigration enforcement and caseworking system within the Home Office. There have already been quite positive steps, with a team of senior caseworkers being established in response to Windrush last year. They are there to provide a bit more discretion—a second pair of eyes—on some of the difficult cases. How do we build that into the system to ensure that there is a safeguard for people who have characteristics that make you think that the person has been caught up without the right paperwork, but would have been covered under the withdrawal agreement? Addressing some of the structural and process questions—assuming that the policy around the hostile environment or compliant environment of enforcement through public services, landlords and employers continues—would seem to be one way. There is also more that can be done with people who end up being the arm of immigration enforcement, such as landlords and employers, through education and outreach. Those are some of the more processy things, rather than questions of policy.
