Coronavirus: World leaders wish Johnson a speedy recovery from COVID-19
US President Donald Trump has said that Americans are praying for Boris Johnson’s recovery.
Mr Trump opened his daily coronavirus news conference at the White House with a tribute to Britain’s prime minister, saying: "I want to send best wishes to a very good friend of mine, and a friend to our nation, Prime Minister Boris Johnson.
"We are very saddened to hear that he was taken into intensive care this afternoon.
"Americans are all praying for his recovery – he’s been a really good friend and something very special: strong, resolute, doesn’t quit, doesn’t give up."
Mr Trump confirmed that his administration has contacted "all of Johnson’s doctors".
And the president said he has asked two leading companies that helped find treatments for AIDS and Ebola to contact London immediately.
Discussing coronavirus, he later added: "When you get into intensive care it really, really gets serious with this disease."
News that Mr Johnson’s condition has deteriorated has been met with well wishes from around the world, as well as from British politicians.
Chancellor Rishi Sunak tweeted to say he was thinking about the prime minister and his pregnant fiancee, Carrie Symonds, and added: "I know he’ll be getting the best care possible and will come out of this even stronger."

"We all wish him a speedy recovery."
Former prime minister Theresa May offered him her thoughts and prayers – and urging people to stay at home, she warned: "This horrific virus does not discriminate."
Mrs May’s predecessor David Cameron told Mr Johnson: "We all want you safe, well and back in 10 Downing Street."
There has also been support from politicians from other parties, including the new Labour leader Sir Keir Starmer, who tweeted to say it was "terribly sad news".
In a post, he said: "All the country’s thoughts are with the prime minister and his family during this incredibly difficult time."

Downing Street said last night: "Over the course of this afternoon, the condition of the prime minister has worsened and, on the advice of his medical team, he has been moved to the intensive care unit at the hospital.
"The PM has asked Foreign Secretary Dominic Raab, who is the first secretary of state, to deputise for him where necessary. The PM is receiving excellent care, and thanks all NHS staff for their hard work and dedication."
