Newspaper headlines: 'Blocking Brexit' and short prison terms 'to end'
Prisons minister Rory Stewart tells the Daily Telegraph that "very short" jail terms are long enough to damage, but not long enough to heal.
Mr Stewart admits his plan - to scrap jail sentences shorter than six months for most crimes in England and Wales - could provoke a backlash from the public and some Conservative MPs, but he insists "it's a debate I have to win".
The paper says the proposal is a significant shift in thinking towards a greater emphasis on rehabilitation, noting that simply jailing offenders has caused the prison population to double to 80,000 since the 1990s.
The Financial Times reports that the Japanese firm Hitachi is on the verge of abandoning a plan to build a nuclear power station on Anglesey, threatening hundreds of jobs.
Sources close to the project in Wylfa tell the paper that Hitachi will announce it is pulling the plug next week because of problems with financing.
The paper says the decision would leave a hole in the UK's energy strategy, as old reactors and coal plants are closed down in the coming decades.
It could also cause a political headache for Prime Minister Theresa May, according to the paper, making it even harder for her to resist further Chinese involvement in the building of nuclear power stations in Britain.
Researchers tell the paper that raised levels of nitrogen dioxide, commonplace around the world, increase the risk of losing a pregnancy by nearly a sixth.
The scientists describe the findings to the Guardian as "pretty profound" and call for toxic air to be cut to protect the health of the next generation.
British tennis player and former world number one Andy Murray is pictured on several of the front pages after he tearfully announced he plans to retire this year because of a long-standing hip injury.
The Guardian reports from Dunblane tennis club, where a coach who taught Murray as a boy describes his grit, determination and sheer will to win even aged seven.
The Times believes that Murray's pain-racked body means he is unlikely to add to his haul of titles in the next few months.
But, the paper says, you never know - he's one of toughest competitors British sport has ever produced.
The Telegraph reports on a development it says would delight Darwin, that African elephants in Mozambique are losing their tusks to evade poachers.
The paper says elephants with no tusks were ignored during a period when 90% of the population was wiped out.
The tusk-less survivors were then able to mate and pass on their genes, resulting in a much higher proportion being unattractive to ivory poachers.
The paper says it is an astonishing example of evolution by natural selection.
"War on the sale of treats" is the headline for the Daily Express.
The paper says a crackdown has been ordered on so-called "sugar mountains", where discounted sweets are piled high in shops, in locations designed to encourage children to pester their parents.
The plans - which the government has put out to consultation - are reportedly prompted by concerns that unplanned sugary purchases are fuelling an epidemic in childhood obesity.
The Financial Times says the European Commission President Jean-Claude Juncker is making a "last-ditch effort" to save Theresa May's Brexit deal ahead of next week's crunch Commons vote.
The offer reportedly could include a promise to limit the backstop plan to avert a hard border in Ireland to no more than a year.
In the Sun, Downing Street is said to be resigned to losing Tuesday's vote, and is apparently battling to keep the margin of defeat to double figures.
And a number of papers report on a new National Lottery draw called Set For Life, which would see the winner receive £10,000 a month for the next 30 years.
The Daily Mirror describes it as a "pension game for millennials", and says the odds of winning are a lot better than other popular lotteries, but still pretty steep, at 15 million to one.
