I am grateful to my medically qualified right hon. Friend for that intervention. He is of course right that that is unlikely. There would have to be some evidence of a very different kind of variant of covid for it to pose any kind of threat of that sort. He is also right to point out that when we first went into a lockdown, it was intended to protect the NHS for long enough for us to increase capacity in the service for a three-week period. The first lockdown then spread into
three months. That is the most important thing the House should be guarding against: the mission creep that allows Governments simply to introduce restrictions and further restrictions, and then extend them, getting into the habit of regulating what we do. That is my most important concern of all.
In the summer of 2020, the Prime Minister said that it was time to move on and time to start to trust people to make decisions for themselves. I rejoiced at that and thought what a wonderful thing it was that we were moving to a point where we would advise people, inform people and make sure they had the best evidence to make decisions in their own lives. Now, however, we see the first instinct of the Government when we do not even have any evidence that the omicron variant is worse in its effects. There is some suggestion from South Africa that it might be less severe, but the Government�s first instinct is to introduce further compulsory measures and regulations relating to self-isolation and to face coverings in some settings but only until 20 December, plus measures that affect the travel industry, particularly the move back to PCR tests on day two.
