Thank you, Madam Deputy Speaker. I welcome these measures, but they do not go far enough to deliver a comprehensive system. The Brazil and South Africa variants have been identified across several continents, and in the first wave, less than 1% of new cases came from China. The overwhelming majority came from European countries that the Government said were low risk at the time. May I ask the Home Secretary about the number of people likely still to be arriving who are not covered by quarantine hotels, who do not have to take further tests on arrival, and who will be able to go straight on to the public transport system from Heathrow or wherever they arrive? Can she confirm that that is likely still to be thousands of people each day, and does she think that that is wise?
