The naming of the two Russian agents accused of the Novichok attacks in Salisbury is the lead for almost every paper - and their pictures appear widely on the front pages.

For the Daily Express headline, they are the "smirking assassins sent by Putin".

But the Guardian says there is no prospect of either ever returning to British soil.

As the Times points out, Russia will never extradite them to Britain, and they may never travel to a country in which the European Arrest Warrant obtained in their names could be used against them.

The Daily Telegraph says it remains unclear how Alexander Petrov and Ruslan Boshirov secured visas to travel undetected, smear Novichok on to the door handle of Sergei Skripal's home in daylight and then discard the bottle it was carried in.

Nigel West - the espionage author - writes in the Telegraph that their identification takes us back to the darkest days of the Cold War, when trained KGB killers were deployed to hunt down defectors - often using theatrical methods of elimination.

Health Secretary Matt Hancock writes in the Daily Telegraph ahead of his speech pledging to bring NHS IT systems into the 21st Century.

He describes them as "downright dangerous" and promises a "bonfire of the fax machines" and outdated technology.

"The fact that your hospital can't see your GP record, or that you as a patient don't have control over your own data, or that even within the same hospital different departments have to write down basic details is expensive, frustrating for staff, and risks patient safety," Mr Hancock says.

Cover your ears

"What is in our food?" the Daily Mail asks, after tests by local councils first revealed by the BBC showed that nearly one in five samples of meat from restaurants and shops contained products from animals which were not on the label.

They included "lamb" korma with a 100% beef, and "pork" sausages with lamb, beef and chicken in them.

The paper says the use of tainted meat appears to be part of a scam across the food sector - mainly involving small independent businesses but also some supermarkets - that is designed to mislead and profiteer.

Consumers have every right to be outraged, it says.

Would you go to a rock concert wearing ear plugs or cotton wool to protect your hearing?

That's what Roger Daltrey - lead singer of the Who - is urging fans to do after saying that fronting "the world's loudest band" made him go deaf.

He tells the Sun he covers his ears when he goes to gigs because he "can't take the volume" - and says fans shouldn't be embarrassed.

"The music sounds just as good if you put a bit of cotton wool in your ears," he promises.

Foam bullets

Finally, a 999 call from residents in a village in Norfolk last weekend reporting the sound of gunfire and screaming children from a neighbouring garden sparked an immediate response by police.

However, the Daily Express reports that when they got to the house in Yaxham, the found a little boy's birthday party was under way.

The Sun says eight-year-old Oliver Green and 18 friends in camouflage caps had been firing foam pellets from plastic guns.

According to the Daily Telegraph, the three officers joined in the celebrations and posed for photos with the children.

The Daily Mirror reports that a force spokesman said no offences had been committed.
