Recommendation 20

We also do not accept the Home Office’s suggestion that no measures were needed after 13 March because imported cases made up only 0.5% of total UK infections. That figure was not calculated until 22 March by which time a million more people had arrived and the epidemic had rapidly escalated in the UK. It is likely to have been substantially higher at the time when guidance was lifted. We set out further concerns about the Home Office reliance on this measurement from paragraph 108.
