My right hon. Friend asks a very important question. In terms of permanency, we are living with this virus; that is a fact. In better news, we are just weeks away from seeing people who have had the vaccine develop immunity, so circumstances are changing. We have known throughout this situation that things change, so we keep all our measures under review—whether it is changes to travel bans for specific countries or other measures, they will always be under review. The Government will not hesitate to take measures when it comes to preventing a new strain from coming to the United Kingdom once it has been identified and making sure that we take the right measures to protect the public. As I have said a number of times, at every stage we will keep the House informed and, importantly, we will make sure that advice is communicated to the British public, so that when things change, including at the border, they are kept informed.
