My hon. Friend is absolutely right. I understand why he raises the importance of regional airports throughout the pandemic. They have played an important role. All airport operators take responsibility for the way in which they work with us, but also for enforcing coronavirus measures and restrictions, such as social distancing and keeping passengers apart, particularly as they go up to PCPs—primary control points—and then come across Border Force officers. It is absolutely right that airports, who are our operational partners, work with us to take responsibility—that shared responsibility I have spoken about so frequently—in terms of checking with the carriers that the passenger locator form is completed, but also to ensure that they themselves put those protective measures in place to stop the spread of the virus.
