British Prime Minister Boris Johnson said he owes his life to the National Health Service staff who treated him for COVID-19, ahead of figures Sunday in which the U.K. is expected to surpass 10,000 coronavirus-related deaths. “I can’t thank them enough,” Johnson said in his first public statement since he was moved out of intensive care Thursday night at St. Thomas’ Hospital in London. While he convalesces, Johnson has asked Foreign Secretary Dominic Raab to handle the nation’s response to the pandemic that has infected at least 1.78 million worldwide and killed 109,000 people.
