In Monday's papers, there is a photo on the front of the Telegraph of the Russian opposition leader, Alexei Navalny, on board the plane that took him back to Moscow yesterday.
He is wearing a face covering - but he seems slightly startled by the journalists surrounding him, wielding cameras and smart phones.
The headline is: "Putin's harshest critic flies into a storm".
He is also on the front page of the Financial Times - pictured in the airport after touching down, with police officers closing in to arrest him.
Both the Express and the Mail lead on the NHS in England starting to send letters to the over-70s, inviting them for their Covid vaccinations.
The Mail's headline is: "Hope in the post for five million". Its leader describes the statistic - that each minute, 140 British people receive a jab - as "truly head-spinning".
But the Express warns readers that no matter how well the vaccination programme seems to be going, "this is not the time for complacency".
In its opinion column, the Times suggests that as the pace of inoculation increases, attention is now turning to "what new freedoms the country will enjoy".
But it too signals a note of caution, warning ministers to do all they can to prevent new Covid variants spreading in the UK.
It concludes that the progress made in recent days is "too exciting to squander".
The Mirror focuses on the government's latest vaccination target, with the headline: "Jabs done by September".
That refers to the suggestion that all adults in Britain could have been offered their first injection by the autumn.
Its leader column states that "shortages and problems with the supply of vaccines seem to have mysteriously vanished, as ministers tout even more ambitious figures".
And it seems sceptical about the language used by the government - pointing out that it "talks as if people given a first jab are inoculated, when immunisation is not complete until the second".
Trump Baby Blimp
The Guardian is one of several papers to report that a 20ft high inflatable caricature of US President Donald Trump - as a scowling infant - is being added to the Museum of London's collection.
It explains that the orange, helium-filled "Trump Baby Blimp" was a focal point for the protests in the city, during his state visit in 2019.
The museum's director explains that it is being included as an example of the British love of satirising politicians. The headline is: "Inflated ego".
The Guardian also looks ahead to the Commons debate later - on whether the government should extend the temporary £20 a week boost to Universal Credit, which was introduced at the start of the pandemic.
It says the Resolution Foundation think-tank has added its voice to those calling for the extension.
The organisation's senior economist tells the paper that the decision "will determine whether millions of households are able to enjoy any sort of living standards recovery next year".
In his obituary of Phil Spector, the Telegraph's music critic, Neil McCormick, says it is hard to know how to feel about the death of such a hugely important, and yet hugely flawed, music industry figure.
"Do we lament one of the legendary architects of modern pop, the original Tycoon of Teen?" he asks.
"Or do we say good riddance to a narcissistic, misogynistic, gun-obsessed, unrepentant killer?"
Finally, the i newspaper marks the forthcoming sale at auction of a demo tape, recorded by the band which became Radiohead, with a round-up of valuable demos that have gone under the hammer.
It says the earliest known tape of Mick Jagger and Keith Richards went for more than £50,000. And a 1958 recording of The Quarrymen, who would become the Beatles, playing "That'll Be The Day" is said to be worth up to £200,000.
