Boris Johnson and Michael Gove both find their names on the front of the weekend papers amid claims the pair sent a secret letter to Theresa May on apparent instructions on how to run Brexit.
The Mail on Sunday says the Prime Minster is "effectively being held to ransom" by the "Cabinet heavyweights" as the leaked letter apparently demands Mrs May makes sure her top team supports their Brexit plans.
Meanwhile, Labour leader Jeremy Corbyn has launched a "blistering attack" in a report by the The Observer, calling for the Foreign Secretary to be sacked for "undermining our country" and "putting our citizens at risk".
And in the Sunday Times, Mr Corbyn demands Mrs May to "govern or go", while the paper also reports on further pressures facing the Prime Minister with 40 Tory MPs said to have agreed to sign a letter of no confidence in Mrs May.
Brexit, too, doesn't escape its front page, with the paper reporting on a warning from Labour MPs that Mrs May faces a "devastating" Commons defeat if she continues to refuse Parliament a meaningful vote on the final deal to leave the European Union.
The Sunday Telegraph also has Michael Gove on its front page, but this time in a story about pledges by the Environment Secretary to set up a a statutory body to deliver a "green" Brexit.
A picture of the Duchess of Cambridge also features on the front page after her attendance at the annual Festival of Remembrance. Kate accompanied the Queen and other royals at the Royal Albert Hall to remember the nation's war dead on Armistice Day.
The Sunday Express, meanwhile, reports on the "Rebirth of UK fishing ports", saying Brexit will revive the industry and create 30,000 jobs, while the Daily Star Sunday claims Soham killer Ian Huntley has bragged he will be our of jail in three years by challenging a rule that means he cannot apply for parole for 40 years.
