Newspaper headlines: Fracking payments and grammar schools
The Sunday Times believes doping is casting a dark shadow over the Olympic Games.
The paper's leader column bases its conclusion not only on the uncovering of Russia's state-sponsored cheating, but also its report that a Kenyan official asked for a bribe to warn athletes in his country about impending drugs tests. He denies the allegations.
The Rio Olympics, the paper fears, will be remembered for all the wrong reasons.
"Will you hit the Frackpot?" asks the Mail on Sunday, which reports on its front page the suggestion by the government that some of the proceeds of fracking developments could be paid directly to people living nearby.
The paper speculates which towns and villages could be in line for windfalls. Households in Kirby Misperton in North Yorkshire, it says, could receive nearly £65,000 each.
The paper calls the proposal "stunning" and says it marks a shift by Theresa May away from David Cameron's "cautious" approach to shale gas extraction.
The Sunday Telegraph also highlights a divergence between the policies of the prime minister and her predecessor.
It claims Theresa May is planning to lift the ban on opening new grammar schools, and says the announcement could be made at the Conservative party conference in October.
The paper says the plan would be welcomed by backbenchers, whom it says ran into repeated resistance from David Cameron on the issue.
Trump campaign focus
Several newspapers reflect on a difficult week for Donald Trump. The Sunday Times reports that Republican party grandees are becoming increasingly exasperated with the tycoon, after he spent days feuding with the family of a Muslim soldier killed in Iraq.
Newt Gingrich - a senior Republican figure once touted as a possible Trump running mate - is quoted as saying Mr Trump is helping Hillary Clinton win, by proving he is "more unacceptable" than she is.
The Observer has spoken to members of Donald Trump's core support. Lei Ann Gleaves who describes herself as a stay-at-home mother from Franklin, Tennessee, says it would take a lot to dissuade her from voting Trump, because she completely distrusts Hillary Clinton.
And Michael Barnett, a lawyer from Palm Beach in Florida, says he is supporting Donald Trump now more than ever, because he is the "real deal" who speaks his mind.
The Observer carries a warning from leading scientists that a key pledge of the Paris climate summit could be almost impossible to keep.
The paper cites Met Office figures showing average global temperatures were 1C above pre-industrial levels for every month in the past year, and close to 1.4C in February and March.
The ceiling set in Paris was 1.5C. The paper quotes a professor tasked with implementing the goals as saying the agreement is "impossible, or at least very, very difficult" to keep.
Ponies in mascara
The Sunday Telegraph reports on concerns in the world of show horses about the growing popularity of equine cosmetics.
The president of the British Show Horse Association tells the paper he "hates this make-up nonsense" and criticises judges for "having the wool pulled over their eyes" in awarding prizes to horses wearing mascara, foundation and false tails.
He blames parents for giving in to their children's demands. The head of a company which sells horse make-up says it should be applied tastefully, or else horses could end up looking foolish.
Finally, many of the papers feature the face of Adam Peaty, the British swimmer who broke his own world record in the 100m breast-stroke in Rio.
He is pictured giving the thumbs-up from the pool on the front of the Sunday Telegraph, and in action, coming up for air, on the front of the Observer.
