On Wednesday, Mr Johnson chaired a COVID-19 meeting before appearing at Prime Minister’s Question’s where he was sitting close to Health Secretary Matt Hancock and Home Secretary Priti Patel.
Mr Johnson has held regular cabinet meetings and emergency coronavirus sessions – however most ministers are believed to have dialled in.
He has also been seen at several of the government’s televised daily briefings in where he has appeared alongside senior medical officials including England’s chief medical officer, Professor Chris Whitty and the government’s chief scientific adviser Sir Patrick Vallance.
Downing Street has previously confirmed that Foreign Secretary Dominic Raab would stand in if Mr Johnson was too unwell to continue.
