Newspaper headlines: 'Show your passport to use NHS'
Unusually, the Guardian, Daily Mail, and Daily Telegraph lead on the same story.
All three papers pick up on Chris Wormald's comments to MPs on Monday.
The Department of Health's top civil servant said hospital patients in England may need to show ID before being treated.
In the Daily Mail, one letter-writer welcomes extra checks on foreign patients.
"The other day I received a hospital appointment letter from Papworth Hospital - nothing unusual in that," writes Bill Hodges from Eynesbury in Cambridgeshire.
"What was unusual was the residency status pre-attendance form I have to fill in.
"One could argue that having to fill in such a form is an invasion of privacy...but at least I know my taxes aren't being spent on free medical treatment for those who aren't entitled to it."
Moths to a Flame
The sketchwriters were in luck yesterday.
There they were, sitting through the Prime Minister's speech to the CBI, when lo! A moth went before them.
"CBI delegates are serious bods but from the hall's media seats there came a distinct sniggering as the moth nearly landed on the Prime Minister's hairdo," writes Quentin Letts in the Daily Mail.
"There was speculation that maybe it had flown out of Mrs May's wallet."
Elsewhere in the media seats, the Telegraph's Michael Deacon was impressed with the Prime Minister's stoicism.
"Ever since she was called upon to lead her country, she has known that she would face many onerous challenges.
"Brexit. The economy. Stage invasions from unruly lepidoptera. Heroically, she soldiered on."
In the Times, Patrick Kidd was concerned for the lepidopteran's wellbeing.
"Not long after its final flap, Mrs May developed a cough, as if she had something stuck in her throat. Surely she had not dealt with it herself?
"That will give fuel to those conspiracy theorists who believe our leaders are lizards."
Six-year-old children are being paid 22p an hour to make Kinder Egg toys, reports the Sun.
The paper says Romanian families "work 13 hours a day" putting the toys together. For every 1,000 they make, they receive £3.80.
According to the Sun, Kinder's parent company, Ferrero, buys the toys from a firm called Romexa.
Romexa sub-contracts the work to other firms. They, in turn, get families to construct the toys in their homes.
One worker tells the paper: "I know the pay is terrible but I don't have any choice.
"We have to get money to eat and look after our children."
Another says: "I will go crazy doing this work. I even see the toys in my dreams."
A manager for Romexa said he had "no idea the work was being outsourced", adding "the pictures suggest we have a big problem".
A spokesman for Ferrero said its suppliers were subject to "regular independent checks", and that it would "investigate these new allegations fully".
Could a solicitor's daughter from Llanover in South Wales become the French first lady?
After Francois Fillon won the first round of voting to choose the Republicans' presidential candidate, the British press profiles his Welsh wife, Penelope.
The Times says Mme Fillon, 60, met her husband while on a year out from her degree. They married in 1980 and have five children.
Meanwhile, the Guardian reports that Penelope's younger sister is married to Francois' brother.
"My father was very pleased I married a Frenchman," the Guardian quotes Penelope as saying.
"But when my sister did the same, he banned our other two sisters from French men."
An engine invented by a British scientist has - on paper - plenty going for it.
By producing thrust without propellant, it would allow interstellar travel and "rip up two centuries' worth of textbooks".
There is, however, one problem. "It breaks at least one fundamental law of physics," reports the Times.
Since Roger Shawyer designed the EmDrive, it has "languished in the outer darkness, some distance beyond the frontiers of mainstream research," the paper adds.
But, in a surprising twist, Nasa has tested the EmDrive - and it works.
"This leaves two possibilities," says the Times. "Either Nasa and its independent reviewers got something wrong, or physics has some serious catching up to do."
Sadly, a lecturer in accelerator physics, Hywel Owen, tells the paper it's probably the former.
