"Will he ever learn?" is the question for the prime minister from an exasperated Sunday People amid concern about the Indian variant.
It says families of Covid victims have accused Boris Johnson of "repeating past mistakes" by failing to restrict travel from India in early April.
The Sunday Times estimates that 20,000 people who could have been infected were allowed to enter Britain from India in the period before the government imposed a travel ban.
One source says the delay was because Mr Johnson did not want to offend the Indian Prime Minister, Narendra Modi, with the UK seeking a post-Brexit trade deal.
Downing Street has denied relations with India had any role in the decision.
The Observer says experts have urged Mr Johnson to reconsider the relaxation of coronavirus restrictions in England because of the variant.
Professor Kit Yates says a two-week delay would make a "huge difference" because it would allow more people to be vaccinated and enable scientists to learn more about the variant.
But the Sunday Express urges the prime minister to channel his inner Sir Francis Drake - who refused to rush a game of bowls before taking on the Spanish Armada - and "stick to his plan", saying we cannot assume variants are going to have a "dramatic effect".
"Royal aides want Harry and Meghan to give up their titles," is the Mail on Sunday's front page headline.
Senior courtiers have told the paper there is a growing sense of "bewilderment and betrayal" over the couple's continued attacks on the royals.
The aides are said to be "particularly incensed" about Harry's criticism of Prince Charles's parenting skills in a podcast interview, and by implication, those of the Queen and the late Prince Philip.
The Sunday Telegraph reports that Culture Secretary Oliver Dowden wants voters from so-called "red wall" seats - won by the Conservatives from Labour in the north of England at the last election - to replace people from "metropolitan bubbles" on the boards of Britain's museums.
In an article for the paper, Mr Dowden says the change will give cultural organisations the confidence "to stand up against the political fads and noisy movements of the moment".
Official figures show that, last year, 50% of chairmen and trustees appointed to publicly-funded institutions lived in London - with the culture secretary now keen to ensure a "grandparent in Hartlepool or Harwich" feels as represented as a "millennial in Islington".
Smelly rubbish could be left to pile up for a month under what the Sunday Mirror calls the "Boris bin plan".
The prime minister wants all councils to pick up food waste, glass and recyclables on a weekly basis from 2023.
But the paper says the fear is the new rules will delay the collection of general refuse. The government says its new approach will reduce landfill.
The Sunday People's verdict is: "This stinks."
And finally, "Wood you believe it" asks the Daily Express as it features photographs of 100 life-sized wooden sculptures of Asian elephants.
The creatures were in London to highlight how humans can better co-exist with animals.
The Express says there were "wild scenes" as the creatures were paraded under the Queen's windows at Buckingham Palace - while the Sunday Telegraph wonders whether they used a "trunk road".
