Re: Seems consistent with my timeline
There were several arguments against closing the borders to non-UK residents. All were wrong.
The first was the economic cost. Compared to what the last 14 months have cost us closing the borders would have been cheap at twice the price.
The second was that people coming from countries with a lower prevalence of Covid would not worsen the problem. This ignored the fact that plenty of other countries' surveillance systems were less effective than the UK's and we had no idea what the true prevalence of Covid in those countries was.
The third was that Track & Trace would work. I think that speaks for itself.
