What exactly was known several days ago? The new variant is one thing, but the analysis that it's spreads more rapidly is another. That wouldn't have been known without detailed examination of the figures.

Mr Johnson said analysis from New and Emerging Respiratory Virus Threats Advisory Group (Nervtag) suggests the new variant could increase the R number - or reproductive rate of the virus - by 0.4 or more.

The NEW evidence suggests that where somewhere had R number of X, the new variant increases that R number by 0.4, eg R number of 0.8 becomes 1.2. Decisions would have been previously made on the understanding of the lower R number.
