I thank my hon. Friend for his question. He is right: we are in a global health pandemic. The daily numbers that we see of people being hospitalised and the impacts of covid are a sobering reminder of all of this. I wish to make a couple of points. Of course passengers are checked at the airports—we have just discussed that today. All airports across the UK are operational partners, and they have a responsibility to comply with those social distancing and covid-compliant measures. We will continue to work with them and support them to do so. As ever, my message again is: people should not be travelling; we are in global health pandemic.
