Newspaper headlines: 'Costa del Quarantine' and princes' 'bitter rift'
"Covid chaos" and "Holiday misery" are just some of the headlines which greet the government's quarantine decision.
The Mail on Sunday says the announcement has left the transport secretary red-faced - as he flew to Spain on Saturday. It adds that Grant Shapps could not be reached for comment, but his mobile did have a foreign dial tone.
"Costa del Quarantine" says the Sunday Mirror as it warns that Britons in Spain have been left blindsided and frustrated by the new travel announcement.
"El Hell!" is the Sun on Sunday's headline. It fears the ruling will be a disaster for an industry just getting back on its feet and it wonders why the Costa del Sol is off limits - when there are far fewer cases there.
In the Sunday Telegraph, one travel expert questions why ministers did not act before Friday, when tens of thousands of holidaymakers jetted off for a Spanish break.
The book describing the rift between the Sussexes and the Cambridges gets plenty more coverage. The Sunday Times lead is drawn from the book it is serialising which gives an account of the breakdown in relations between the Duke and Duchess of Sussex and the royal family.
It headlines the claim that Prince William behaved like a snob when Prince Harry fell in love with Meghan.
The Mail on Sunday says it has heard from friends of the Cambridges who reject claims the couple had been unwelcoming towards Meghan - insisting they had rolled out the red carpet for her.
Andrew Morton, whose 1992 biography of Princess Diana sent shockwaves through the Royal Family, thinks there is no way back for Prince Harry and Megan now. He tells the Sunday Mirror that Diana would be devastated to witness the breakdown of Prince Harry's relationship with Prince William.
More favourable coverage of the royals can be found on the front of the Telegraph. It features a new portrait of the Queen, wearing a blue dress and sitting in the white drawing room at Windsor Castle. Beside her there's a tea cup placed on an ornate table.
The Queen watched via video-link as the picture was unveiled at the Foreign Office - and immediately noted a small omission - the cup is in need of a refill.
Labour is facing fresh legal action over anti-Semitism, according to the Observer - with nine current and former members claiming the party broke data protection and privacy rules.
The group all lodged confidential complaints about cases of anti-Semitism but they were angered when their names were leaked in a report written by party officials loyal to the former leader, Jeremy Corbyn. The paper says the party has already been warned about its finances - and the cases could cost it millions if it loses.
'Learn from mistakes'
The Sunday Times calls for the UK to learn from its Covid mistakes - and swiftly. It welcomes the prime minister's change of tone during a BBC interview on Friday but says he should not be allowed to get away with what it calls "his stock excuse" - that during the early stages of the crisis nobody knew the extent the virus was being passed from person to person.
The paper says this was a hot topic among government scientists from late January onwards and it calls for a quick parliamentary inquiry to make sure the country is ready for a second wave.

The Observer covers the initiative to prescribe cycling as a way of tackling obesity, saying for it to work officials realise people will need to feel safer on bikes in urban areas.
But the Sunday Telegraph highlights problems with the new segregated cycle lanes and other green policies in the transport secretary's own constituency of Welwyn in Hertfordshire.
It says shopkeepers have been complaining to the transport secretary that visitors are no longer coming by car - turning it into a "ghost town".
There has been a middle class revolt with vigilantes dismantling the red-and-white barriers used to widen pavements - and Mr Shapps himself has complained they are not suited to the old layout of Welwyn.
