A slogan can come back to haunt you. For Boris Johnson, the words ‘data not dates’ sounded powerful at a time when Covid cases were high and hospitals full. The idea was that the government would be guided by scientific reason, would respond to the figures and would not let rigid targets dictate policy. Since the Prime Minister announced his roadmap at the end of February, however, ‘dates’ seem to have become far more important than ‘data’. How can he claim to be following the data when he will not budge from a timeline which now looks like it was designed for a different phase of the pandemic? Why were people braving the cold and rain outside restaurants on a bank holiday when there is every chance it’s safe to go inside? There is nothing in the data, we are told, to suggest we should further delay the dates laid out in the roadmap.
