Newspaper headlines: NHS 'chaos' and council house plans
Many of Sunday's papers report on the international hunt for the hackers who disrupted NHS computers in what the Sunday Telegraph calls the biggest cyber attack in history.
The newspaper says crime agencies are understood to be seeking two separate gangs - one with links to the Kremlin, the other a crime syndicate which has tried to hold hundreds of organisations to ransom.
Several papers accuse the NHS of being ill-prepared for the attack.
The Mail on Sunday believes bad management was the real culprit, adding that no-one seems to have found comparatively small amounts of cash to modernise worn-out and hopelessly insecure systems still used by nine out of 10 health trusts.
The Sunday Times says the key to good cyber-security is keeping the door locked against hackers. In too many NHS trusts, it claims, the criminals were allowed to walk right in.
And The Observer says the attack was foretold and there are lessons the public sector needs to learn about IT security, when malware can be bought for the price of a curry.
Council house bid
The Sunday Times leads with the Conservative plan for thousands of new council homes, calling the proposal an audacious bid to woo Labour voters.
The newspaper says the plan to offer some of the homes for sale under a "right-to-buy" scheme emulates Margaret Thatcher's dream of a property-owning democracy.
Labour's plans to raise billions of pounds by imposing a so-called Robin Hood tax on financial transactions are condemned by the Sunday Telegraph as "fiscal folly".
The newspaper believes such a levy would would be a disaster, saying investors large and small would pay the price, whilst traders and banks would move vast swathes of their operations out of the UK.
But the Sunday People welcomes the proposals. It believes the huge sums passing through the City mean the tax would hardly be felt and money would be raised to keep cherished services running.
And the Sunday Mirror says the proceeds would help pay for schools and hospitals. It concludes that the kind of people who don't like the plans are the kind who don't like paying their fair share of tax.
As the Royal College of Nursing meets in Liverpool, the Sunday Express reports that its leaders are to discuss strike action for the first time in its 100-year history.
The newspaper says senior RCN members, who are worried about falling pay and increasing pressure, hope the threat of strikes will ensure the new government acts on their key demands after the general election.
The Sunday Times says the sacked FBI director, James Comey, is poised to exact his revenge on President Trump by testifying against him publicly before Congress.
The newspaper says Mr Comey has been vilified and threatened by the president, and has told friends he wants to strike back in an open session.
It reports that it could be one of the most-watched events in US political history.
And the Sunday Telegraph reports that the Anglican Church has been experiencing a small increase in congregation numbers.
The newspaper says an academic, who analysed two social surveys, found just over 17% of people questioned saying they were Anglican worshippers - a rise of almost a percentage point since 2009.
The Bishop of Liverpool, the Right Reverend Paul Bayes, describes it as a gentle increase, but says it shows that the Church's message remains attractive in an increasingly self-centred and lonely world.
