Many of the front pages carry photographs showing the smiling faces of some of those who died at Gosport War Memorial Hospital.
"Condemned to die by their hospital" is the headline in the i while the Daily Mirror calls Gosport a "hospital of horrors".
The Sun says families have condemned the scandal as "horrific, calculated and shameful" and have "demanded criminal charges against medical staff who allowed their loved ones to be give lethal doses of painkillers".
Some relatives speak of their own feelings of regret that they did not intervene. Pamela Byrne, whose stepfather Clifford Houghton died at the hospital, tells the local newspaper Portsmouth's The News "there is a little bit of guilt there, because you feel, why wasn't I able to do anything?"
In its editorial, the Times says the case has prompted serious questions about how widespread such practices may be.
"When hundreds of patients are given fatal heroin overdoses in an NHS hospital and it takes decades to get to the truth, the entire system is in the dock," it says.
The Daily Mail offers a similar warning.
It says the Gosport cases - coming after the scandal of unnecessary deaths at Mid Staffordshire hospital - suggest an "institutional contempt for the elderly".
It is a time for "deep soul-searching" within the NHS, it adds, "over its attitude to whistleblowers and the value of old people's lives".
The columnists reflect on the promised rebellion that failed to materialise when MPs voted on whether they should have a meaningful vote on the final Brexit deal.
In the Spectator, Isabel Hardman says the events seemed all too familiar - "one of the laws of Brexit is that every Commons division and Cabinet meeting billed as being a 'crunch vote' ends up postponing the crunching again, and again and again".
PoliticsHome says the decision of the Tory MP Dominic Grieve not to vote for his own amendment caused consternation among Labour and Lib Dem Remainers.
One Labour source tells the website Mr Grieve "raised more white flags than a regatta".
"Grieve budges as May fudges" is how the Sun sums up the day's events at Westminster.
In the Guardian, John Crace describes Mr Grieve as "the rebel who forgot to rebel," concluding that "indecision and duplicity... won the day again".
The Times says it has learnt that Donald Trump and Vladimir Putin are preparing to meet during the US president's visit to Europe next month.
Senior British government sources have told the paper the meeting could take place before Mr Trump attends a Nato summit and visits London.
The prospect is fuelling fears in Whitehall, they say, about Mr Trump's commitment to the military alliance.
Several papers report that the chief inspector of schools is to back calls for mobile phones to be banned in schools.
According to the Daily Telegraph, Amanda Spielman will tell audiences at an education festival tomorrow that she has "yet to be convinced of the educational benefits of all day access to Snapchat and the like".
The Daily Express says she will also signal her support for a return to some "old-school punishments".
She will say it is "entirely appropriate" to use sanctions such as writing out lines, playground litter-picking and detention to tackle bad behaviour.
A four-year analysis of around 800m posts on Twitter suggests most Brits wake up "full of drive, positivity and vim."
Sixteen hours later, it reports, our thoughts often turn to "anger, swearing and existential dread".
The paper suggests workplaces across the nation could learn from the study by allowing staff to take power naps, adding if they want "alert and smiling staff, they should issue pillows to all employees".
