Johnson, 55, was admitted to St Thomas’ Hospital on Sunday evening with a persistent high temperature and cough, and was rushed to intensive care on Monday where he spent three nights receiving treatment.
“The prime minister has been moved this evening from intensive care back to the ward, where he will receive close monitoring during the early phase of his recovery,” a spokesman from his office said in an emailed statement.
Johnson was the first world leader to be hospitalised with the coronavirus, forcing him to hand control of the world’s fifth-largest economy to foreign minister Dominic Raab just as Britain’s outbreak approaches its most deadly peak.
Raab tweeted that the improvement in Johnson’s condition was “the news we all wanted to hear”. U.S. President Donald Trump described it as “great news”.
The United Kingdom is entering what scientists say is the deadliest phase of the outbreak, with deaths expected to continue to rise over the Easter weekend.
But in a sign the shutdown measures were working, health officials have said the number of coronavirus infections and hospital admissions had begun to show signs of flattening.
Police said they would be taking tougher action to do just that before the four-day Easter holiday weekend because many people were continuing to ignore the ban on social gatherings.
