The Government are moving forward on the implementation of the withdrawal agreement, and we are confident that the deal will be ratified on 31 January. Under the terms of the agreement, we will enter the implementation period following 31 January, during which medical supplies will continue to flow as they do today. My hon. Friend makes a good point about EU nationals working in the health service. Since the referendum, almost 7,300 more European nationals have been working in NHS trusts and clinical commissioning groups, which should be welcomed.
