The Sunday Times leads on further attacks by David Cameron on his former colleagues, in extracts from his memoir.
The paper says the stiffest criticisms are reserved for Michael Gove, who according to Mr Cameron became “an ambassador for truth-twisting age of populism” during the EU referendum campaign.
And Prime Minister Boris Johnson is said in private conversations to have raised the possibility of holding another referendum after fresh negotiations with the EU.
The Times believes this could damage Mr Johnson – who now says he’s strongly opposed to a second vote.
The revelation from the former rugby player Gareth Thomas that he is HIV positive is the main story for the Sunday Mirror.
Thomas tells the paper that after being diagnosed he sobbed in the arms of his doctor fearing he would die.
He says, like many people, he had associated HIV with death and frailty – and is speaking out to break the stigma.
The former British and Irish Lion explains to the Mirror that he is now fitter than when he played rugby – with the virus all but undetectable thanks to daily medication.
The paper’s editorial praises Thomas, calling him a “shining star” for those struggling with the same stigma.
The government is planning to introduce longer jail sentences for the most violent offenders, according to the Sunday Telegraph.
The paper says that under the plans, child murderers would never be released from prison, and prisoners would have to serve two-thirds of their terms to be eligible for release, up from half at the moment.
A government source tells the Telegraph that most people think political parties and the courts have lost the plot on sentencing, adding, “We agree with the public.”
In what the Mail on Sunday calls a “surreal comparison” Mr Johnson – in an interview with the paper – vows the UK will break free from the EU “like the Incredible Hulk”.
Driving home the point, the prime minister explains “the madder Hulk gets, the stronger Hulk gets”.
The newspaper says his “extraordinary rallying cry” comes ahead of a “crunch meeting” with the European Commission President Jean Claude-Juncker in Brussels tomorrow.
Mr Johnson tells the paper the most important message he will bring is that Brexit will be delivered by 31 October despite the “kerfuffle” in Parliament.
The Sunday Express has carried out a poll which it says shows that Britain has lost faith in its MPs.
Of the 2,000 people surveyed by ComRes, 80% believe Parliament is in desperate need of reform, the paper says, while 60% think MPs haven’t respected the result of the EU referendum.
The Express’s leader column says most people would agree with the sentiment expressed by Oliver Cromwell in 1953, when he told parliamentarians “In the name of god, go!”.
