Yes, of course, we have been not only watching for mutations but, indeed, testing for mutations throughout, and it is partly because the UK has the biggest genomic testing capability of any country in the world that we have been able to pick this one up. There may be new mutations in other countries that do not have this scale of genomic testing, and just under 50% of all the sequenced genomes of covid-19 that are deposited with the World Health Organisation are deposited by the UK because of this capability.
That leads to a challenge, which is that it is the countries that have the genomic testing capability that spot the new variant and report it. There are countries that may have variations that are not known about and are not discovered in this way and cannot be reported, but that is the nature of the pandemic. My strong view is that we should be transparent and clear with our international friends when we find a new variant that is difficult to deal with.
When I have previously come to ask for the House’s support for national restrictions, we had to take it on trust that there would be an exit, because it was before a vaccine had been approved. Today I come to the House seeking approval of these regulations knowing, from the huge pressure on the NHS right now, that this action is necessary today, but also with the certain knowledge that we have a way out.
Before turning to the detail of the regulations, I want to set out the plan for how we get out of them, because that is critical. This country was the first in the world to deploy not one but two vaccines, and more than 1.3 million people have been vaccinated already, including a quarter of the over-80s.
