Newspaper headlines: Euro 2016 plot and MPs 'could defy EU vote'
A far-right "fiend" who was reportedly planning to attack fans at the Euro 2016 football tournament makes headlines in several of Tuesday's papers.
The Sun names him as Frenchman Gregoire Moutaux, and says he had weaponry including TNT, detonators, rocket launchers, Kalashnikovs and 5,000 rounds of ammunition.
Metro says the farm worker also had 20 balaclavas when he was stopped in his van as he tried to cross from Ukraine into Poland.
"He was armed to the teeth and ready to strike," according to a source quoted in the Express.
The Times says the arrest has led to "growing concerns about security" at the tournament in France, while the Mirror calls it a "dire warning for security services".
It notes that weapons can be "readily obtained in warzones by disturbed individuals", but says "good detective work and vigilance" will hopefully keep fans safe at Euro 2016.
'Make vote convincing'
With the EU referendum just over a fortnight away, the debate continues to be the focus for many editors and columnists.
The Times leads with the news - first reported on Monday by the BBC's James Landale - that pro-European MPs will fight to stop Britain leaving the single market even if the public backs Brexit.
It says fewer than 200 of Parliament's 650 MPs support the Leave campaign, and the pro-Remain majority could "shape the means of exit" in dozens of Commons votes as Britain "disentangles" itself from the EU.
In an editorial, the Times says there can be "no question" of MPs defying the will of the British people - but it says Brexit campaigners lack a "coherent" vision for Britain outside the EU.
"The House of Commons will not be violating the will of the British people in preserving membership of the single market if Brexit campaigners refuse to be straight with the voters about their alternative," it concludes.
But the Sun says Remain campaigners have been accused of trying to "fiddle the result".
The Telegraph says a high turnout is essential to prevent Remain campaigners claiming a vote to leave the EU lacks a "popular mandate".
It urges readers to register and "make this vote convincing".
The Guardian also calls on readers to register - today is the last day to do so - and it urges them to reject a "Farage-style Britain" by voting to remain in the EU.
What the commentators say
Several papers report on a dossier of 50 offenders who have, according to justice minister and Vote Leave campaigner Dominic Raab, used EU rules to avoid deportation from Britain.
The dossier contains the "most serious offenders who have been allowed to remain in the UK because of EU red tape", the Telegraph reports.
"It's just criminal" declares the Sun's headline, as it says the EU has been accused of putting lives at risk by "forcing the UK to harbour foreign killers, rapists and drug dealers".
The Express says it proves "we must take back control of the system by voting to leave".
The Mail echoes this view, adding that the dossier shows the "real price of free movement".
Children at a Bristol primary school returned from their half-term break to find a picture by celebrity street artist Banksy on a wall, the Mail reports.
He left a note thanking them for naming a house after him, and added: "Remember - it's always easier to get forgiveness than permission."
The note began "dear caretaker" and said the work was a "present", the i says.
A spokesman for the artist confirmed the work was genuine, it adds.
- Japanese boy left in forest forgives father: The father of a seven-year-old boy who was left in a forest as a punishment says his son has forgiven him, the Telegraph reports.
- When I'm Queening windows: Ukulele king George Formby has been revealed as the Queen's "all-time favourite music act", the Sun says.
- Yorkshire's vegan coach hurls bouncer at sponsors: The Times reports Jason Gillespie, coach of Yorkshire County Cricket Club, has questioned his sport's use of leather balls and has said he hopes the entire dairy industry will be shut down - angering Wensleydale Creamery, a sponsor of the club.
- Women-only clubhouse for Glastonbury: A venue called the Sisterhood - described as a "revolutionary clubhouse" open to "all people who identify as women" - will feature at this year's Glastonbury Festival, the Guardian reports.
'Proceed with caution'
Plans for growing human organs in pigs are debated in several papers, including the Daily Mail.
It quotes a leading UK geneticist who says growing the organs for transplant is "ethically no worse than eating bacon".
But in a column, AN Wilson argues that the creation of "pig-human chimeras is a horror from which all decent people should recoil".
Writing in the Telegraph, bioethicist John Harris says there is "no good reason... for not pursuing the science to the point at which we are able to judge just how safe or unsafe using such techniques in animals, or their fruits in humans, will be".
A Times editorial agrees, saying scientists should "proceed with caution towards what may be an extraordinary new dawn".
If this debate has made bacon sandwiches less appealing, reports in several papers suggest a healthy alternative may be a "Mediterranean diet" rich in fats from olive oil and nuts.
A study by Spanish researchers has found that such a diet does not cause people to gain weight, the Guardian reports.
The "fear of fat is misplaced", the researchers argue, and healthy fats such as those from vegetables and fish should go "back on the menu".
