In a video posted on Twitter on Friday, the British prime minister, Boris Johnson, confirmed he had developed mild symptoms – “a temperature and persistent cough” – over the last 24 hours and, on the advice of the chief medical officer, he took a test which returned positive for coronavirus.

Johnson, 55, said he was now self-isolating and working from home. He said thanks to “the wizardry of modern technology” he would continue to lead the national fightback against the virus.

He thanked the NHS and everybody working to keep the country going through the pandemic and remained confident the UK would beat the virus. He reiterated that staying at home was fundamental to stopping the spread of the virus.
