A number of the front pages feature Rishi Sunak's speech, due to take place on Monday. The Daily Telegraph focuses on the prime minister's claim that - as the world enters one of its most dangerous eras - Britain would be safer under the Conservatives than under Labour over the next Parliament. The paper says Mr Sunak will highlight "dividing lines" between the two parties, including what he sees as Labour's "failure" to match his commitment to increase defence spending to 2.5% of GDP by the end of the decade.
The Times concentrates on Mr Sunak's warning about autocratic states. He is expected to say collusion between China, Russia, North Korea and Iran poses the most dangerous threat since the end of the Cold War - and the West must face up to these adversaries.
The Daily Mail says it will be a "landmark" speech, highlighting the challenges of AI, migration and "authoritarian states".
The Guardian carries a warning from England's former chief medical officer, Dame Sally Davies, that Covid-19 will "look minor" compared with increasingly drug-resistant superbugs. Dame Sally - who is now the UK's special envoy on antimicrobial resistance - says the issue is more "acute" than climate change. It would be a "disastrous picture," she says, if the world fails to tackle the problem. The paper says drug resistant infections already kill at least 1.2 million people a year.
The main story in the Times is a new study of workers across Europe which shows that people take more sick days the heavier they are. The research - carried out by academics in Austria - looked at data from more than 122,000 people across 26 European countries. It found that those who were obese were twice as likely to take time off than people who were a healthy weight.
The paper argues that with 2.8 million people signed off work in the UK, absenteeism among people who are overweight is fuelling a "worklessness crisis" in Britain which is stifling economic growth. The government has announced measures to encourage people back to work.
According to the Guardian, Sir Keir Starmer is under pressure from the Trades Union Congress (TUC) over Natalie Elphicke's defection from the Conservatives. The union's president Matt Wrack is reported to have written to the Labour leader at the weekend, saying Ms Elphicke's support for anti-strike laws - seen as recently as March - should be "incompatible" with the party whip.
The Daily Telegraph says it understands that the Lib Dems have been reported to the equalities watchdog for allegedly deselecting a candidate because of his Christian faith. David Campanale, an Anglican former BBC journalist, is set to be replaced as the prospective MP candidate for Sutton and Cheam after allegations he did not sufficiently disclose his faith during the selection process - a claim which he denies. A Lib Dem spokesman said the party was home to people of all faiths, and none.
And the i cites new data revealing that more than a million people have taken out mortgages in the past three years, which will "last into their late 60s". A former pensions minister tells the paper borrowers are at risk of poverty in old age.
