Mr Johnson is embarking on a charm offensive, says the i paper, which reports the PM's attempt to "rebuild relations" with his backbenchers - even as he self-isolates. An overhaul at No 10 "follows tears, tantrums and text messages in Downing Street soap opera", the paper adds.
"We just want to hug out children" is the Daily Mail's headline, as it describes how parents have been unable to see children in care homes during the pandemic. The Mail's Christmas campaign is urging ministers to help reunite families for the festive period.
The news of Mr Johnson's notification "will raise questions over how rigidly No 10 has been following social distancing rules and minimising contacts" during England's lockdown, says the Times. The paper also reports that charges for using Britain's roads are being considered by Chancellor Rishi Sunak as the government eyes a potential tax shortfall following a switch to electric vehicles.
Meanwhile, the PM will walk away from EU trade talks unless the bloc "gives up its bullying demands", says the Daily Express. The paper says Mr Johnson is "running out of patience" as a deadline for a deal draws near.
Boris Johnson entering self-isolation after being in close contact with a positive Covid-19 case leads Monday's front pages. The Daily Telegraph says the PM's plans for a "reset" of No 10 have been thrown into "disarray". Downing Street's Covid-secure measures are also under scrutiny, the paper adds.
The PM's self-isolation comes just at the moment he was embarking on a "crucial week", says the Guardian. Mr Johnson was hoping to "project an air of competence" after vicious infighting within his top No 10 team, the paper adds.
Mr Johnson is "well" and has no symptoms, the Metro reports, as the paper notes self-isolation guidance means the PM could be cooped up at home until 26 November. Elsewhere, the paper carries tributes to England goalkeeping great Ray Clemence and the entertainer Des O'Connor who both died on Sunday.
