Soon after Queen Elizabeth’s rare speech, the government said the prime minister, who is infected with coronavirus, had been admitted for tests.
Prime Minister Boris Johnson was hospitalized on Sunday evening after 10 days of battling the coronavirus, unnerving a country that had gathered to watch Queen Elizabeth II rally fellow Britons to confront the pandemic and reassure them that when the crisis finally ebbed, “we will meet again.”
The British government said that Mr. Johnson would be undergoing tests and that he would continue to carry out his duties.
But the uncertainty generated by his persistent illness underscored the sense of crisis that led the queen to address the country in a rare televised speech that evoked the darkest days of World War II.
“I am speaking to you at what I know is an increasingly challenging time,” the queen said. “A disruption that has brought grief to some, financial difficulties to many, and enormous changes to the daily lives of us all.”
Her remarks were taped at Windsor Castle, where she has sequestered herself against a virus that has infected at least 40,000 people in Britain, including her eldest son and heir, Prince Charles, and other senior British officials besides Mr. Johnson.
