US President Donald Trump has said that all Americans are praying for UK Prime Minister, Boris Johnson, after he spent a night in hospital.
Johnson was admitted to the unnamed facility for routine tests after suffering from Covid-19 for 10 days.
Trump was among a number of international political figures to pass on their best wishes.
At a media briefing, President Trump said: “I want to express our nation’s well wishes to Prime Minister Boris Johnson as he wages his own, personal fight with the virus.
“All Americans are praying for him; he’s a friend of mine and a great gentleman.
“I’m hopeful and sure that he’s going to be fine,” the president continued.
Johnson had been due to end his seven days’ self-isolation on Friday, but remained behind closed doors after continuing to feel unwell.
