The main story for Guardian and the Times is that Britain is making plans to submit an extradition request to Moscow for two Russians suspected of carrying out the Salisbury poisonings.
Citing security sources, the Times says Scotland Yard detectives are understood to be confident they have identified the suspects and the request is part of the plan to renew pressure on the Kremlin over the nerve agent attack.
But the Guardian says Russia is certain to reject it, prompting another round of tit-for-tat diplomatic expulsions.
For its main story, the Daily Telegraph says the government is planning to make it possible for victims and members of the public to challenge sentences handed down to paedophiles who download or share child sex abuse images.
Solicitor General Robert Buckland has told the paper they should be dealt with by the courts as harshly as those who abuse children.
The paper says official figures show that the proportion of online sex offenders jailed has halved in the past 10 years.
According to the lead in the Daily Express, senior Labour MPs have been plotting to oust Jeremy Corbyn during at least two secret meetings at a country farmhouse in East Sussex.
It says the plot involves a core group of about 12 "moderate" MPs.
A source at meetings is quoted as saying: "We are getting together regularly to discuss how to take back control of the party. At some point, the Corbyn leadership is going to fail and collapse and we need to be ready to step in."
A Police Federation survey suggesting that one in 12 officers has taken on a second job because they cannot afford to pay the bills, is widely reported.
The Independent website says the roles include becoming driving instructors, personal trainers or leasing properties.
It reports the Police Federation as saying some officers have had to resort to food vouchers and welfare schemes while dealing with unprecedented demand for their services, rising violent crime and terrorism.
Too much sleep
Shoppers are being warned to expect higher prices for vegetables because the heatwave is damaging crops and leading to shortages.
The Daily Mirror reports that yields of lettuce, onions, broccoli, cauliflower and carrots are all down.
According to the Daily Mail, produce is smaller than normal, and as a result, growers have asked retailers to relax their rules on the size and shape of vegetables they will accept.
It says a study suggests that people should worry more about getting too much sleep than not enough - because it could be a sign of hidden diseases.
Scientists found that - over the duration of the research, carried out between 1970 and 2017 - people had an increased risk of dying of a stroke or heart attack if they had more than eight hours a night.
The study was led by Keele University and covered three million people.
Finally, the Daily Telegraph says people heading abroad for their summer holidays are less likely these days to pack the once popular phrasebook with their suncream and flip-flops.
According to the Telegraph, research conducted by the British Council found that more than 60% per cent of 16 to 34-year-olds now use translation apps on their smartphones to help understand the local language, with just 39% opting for a phrasebook.
The results of the study come with some advice on social etiquette.
Vicky Gough, of the British Council, tells the paper it is worth learning a few phrases before leaving home - as "nobody wants to be staring at their phone screen all holiday".
