British Prime Minister Boris Johnson’s chief adviser, Dominic Cummings, is the latest senior government figure to show symptoms of the new coronavirus.
Johnson’s office says Cummings developed symptoms over the weekend and is self-isolating at home.
Johnson announced Friday that he has tested positive for COVID-19 and has mild symptoms. Health Secretary Matt Hancock has also tested positive, while the chief medical officer of England, Chris Whitty, says he is self-isolating after showing symptoms.
Senior U.K. officials have been criticized for continuing to hold face-to-face meetings until recently, even while urging the rest of the country to stay home and avoid all but essential contact with others.
Cummings is a controversial figure — a self-styled political disruptor who helped lead Britain’s pro-Brexit referendum campaign in 2016.
He has been blamed for briefing journalists that the U.K. was seeking “herd immunity” against the coronavirus by letting most of the population get it. The government and its scientific advisers deny that was ever their strategy.
