LONDON (Reuters) - British Prime Minister Boris Johnson, who has been criticized for acting too slowly in the COVID-19 pandemic, said on Friday there may have been things he could have done differently. “Maybe there were things we could have done differently and of course there will be time to understand what exactly we could have done, or done differently,” he told the BBC. Johnson has come under fire from critics over his handling of the pandemic, from the high official death toll of over 45,000 and the slow roll-out of testing to a later lockdown than many other countries.
