Immigration (European Economic Area Nationals) (EU Exit) Order 2019

My Lords, following on from the point made about stamps in passports, and as a procedural point, would the Minister confirm that all persons exiting the UK are now properly registered as having left the UK? There was a point in recent times when that was not the case. There were stamps for entry, but I understand not for exiting. Clarification at an appropriate time would be helpful.
