Tymoshenko in Kiev and the Scottish independence debate
Photographs of former Ukrainian Prime Minister Yulia Tymoshenko addressing opposition supporters in Kiev are splashed across the front pages of Sunday's newspapers.
Her appearance in Independence Square came just hours after MPs voted to oust President Viktor Yanukovych and she was released from detention.
But the Observer is among those to highlight the "dangerous days ahead" for the "new Ukraine".
"While Tymoshenko's ordered release is to be welcomed, it should also be recalled that the two-time prime minister is a flawed figure," the paper says in an editorial.
"Then there is the fundamental issue that Ukraine must negotiate: how a country that has political and trade links with both Europe and with Russia finds a balance between the two forces pulling on it from outside?"
The Sunday Times, which uses as its headline Ms Tymoshenko's proclamation that "the dictatorship has fallen", agrees that a "desperately uncertain phase" is emerging.
"The question haunting the West as well as Ukraine is how far President Vladimir Putin will go to keep the splintering nation within the Russian sphere of influence - and whether the West is as tough-minded in defence of its interests as he is in defence of his own," it asks.
The Sunday Telegraph describes the hero's reception for "Ukraine's Iron Lady" and says "crucially" she has "kudos not only on Independence Square but also in Moscow".
Writing in the paper, the UK's former ambassador to Moscow, Tony Brenton, says "Ukraine is not doomed. It has a democratic, constitutional order that so far continues to function...
"There is every reason to feel Ukraine can be put back on the road to a prosperous future. But we need to work with Russia to do it".
'Secret theme park'
There are more photographs from Ukraine in reports focusing on events earlier in the day when opposition supporters turned up at the former presidential palace outside Kiev.
Families found President Yanukovych's Mezhyhirya estate had a "secret theme park" complete with a full-size replica of a Spanish galleon, the Sun on Sunday says.
Reporting from the scene, the Mail on Sunday's Ian Birrell writes "they drove, walked and cycled in their thousands to marvel at Viktor Yanukovych's private residence, with its zoo and manicured 340-acre grounds.
"The same sentiments were heard again and again. 'Look at all this luxury. All our taxes were stolen here'."
According to the Sunday Times, "They found a display of vulgarity that was part presidential palace in the style of the former Romanian dictator Nicolae Ceausescu, part the crazed whimsy of Michael Jackson's Neverland ranch".
"It was not just the size of it... Nor the private zoo, complete with its own peacocks... It was the fact that they had never imagined anything like this even existed."
In another story related to the political crisis of the last few weeks, the Daily Star Sunday reports that the UK Foreign Office has said it was reviewing all trade deals with Ukraine amid claims British weapons were used by police snipers to shoot demonstrators.
As David Cameron prepares to hold a special Cabinet meeting in north-east Scotland, the referendum on Scottish independence continues to provoke comment.
Remarks by the prime minister on what he says is the importance to Scotland's oil industry of staying in the UK are reported on the front page of both the Observer and Sunday Telegraph.
The Sunday Telegraph notes the future of the North Sea fields is central to the debate over independence and has already proved highly contentious.
Meanwhile, the Observer is among the papers to call for "fewer insults and a more informed discussion" on the issue.
"It would be good to hear the positive, uplifting and exciting aspects of both nationalism and the union, not least because, whatever the vote, the English and the Scots will need to live side by side," it says.
"The way in which Westminster ranks closed was choreographed to intimidate and disconcert that section of Scottish opinion that is worried about the uncertainty of a big change," its editorial says.
"But the argument against a currency union requires a more persuasive response than a complaint that the other side is trying to win.
"The SNP needs to respond, over the next seven months, with the same commitment, confidence and attention to detail."
Singer David Bowie's call at last week's Brit Awards for Scotland to "stay with us" - delivered through a message read on his behalf by model Kate Moss - has inspired "no" campaigners, the Sun on Sunday says.
The Better Together campaign is said to be hoping to enlist stars of sport and showbusiness to bolster its case.
Its leader, the former chancellor Alistair Darling tells the paper: "This debate can't be confined to exchanges between politicians. For too many people, that's a turn-off.
"David Bowie and others who have spoken, and will speak, have got people enthused about the issue."
It is a sentiment that would seem to appeal to the Sunday Express, which carries news of a UK-wide poll it commissioned in which 58% of the respondents said the whole country should have a say on Scottish independence.
In an editorial, the Sunday Express says the UK is a nation of "untold advantage, tolerance and opportunity. It would be nothing short of tragic were this to end. Yet end it could if Scotland decides to leave the union.
"It seems bizarre that the Scots alone will have a say in a decision that would affect us all."
A photograph of holidaying shadow environment minister Barry Gardiner in his swimming trunks and up to his waist in water in a Cancun, Mexico, swimming pool features on the front page of the Mail on Sunday.
The paper's headline says the MP "Red Ed's Flood's supremo" was "hard at work... as Britain counts cost of the deluge" after the recent floods. He explains he was invited to the resort to make a speech while parliament was in recess.
Turning to news of a different trip, the Daily Express reports that Australia's incoming governor general has "let slip" that Prince George will be accompanying the Duke and Duchess of Cambridge on their official visit down under in April.
The royals did not confirm whether their new son would travel with them when the plans were announced last year.
On its front page, the Sunday Express reports that nearly four million households across Britain that paid for electricity through time-of-use tariffs may have been overcharged for electricity because of faulty meter clocks.
According to the paper, it could result in suppliers having to pay compensation which it likens to the payouts to people mis-sold payment protection insurance by the banks.
The Sunday Telegraph reports that tens of thousands of pupils in England face losing the automatic right to a place at their local secondary amid a surge in comprehensives using lottery-style admission policies.
"It hardly seems fair. But the schools that use these Byzantine methods would argue that the alternative is not particularly fair either," the paper says explaining in its leader that wealthier parents buying into the catchment area of a good state secondary results in the schools becoming "more socially exclusive".
"In the long term, the only solution is to raise the overall standard of education," the Telegraph adds.
A Sunday People story claims the government changes to housing benefit entitlement for council tenants with a spare bedroom could have been wrongly applied to 40,000 people. It says a loophole applies to more households than previously thought.
Police should be given greater powers to stop people traffickers, the Sunday Mirror says in an editorial.

Finally, a front page story in the Sunday Times headlined "Don't Cry for Me, David Cameron" says lyricist and former Conservative Party supporter Sir Tim Rice has donated money to UKIP.
It says the man behind Evita and Jesus Christ Superstar decided to give up to £7,500 to the party last year after a meeting with party treasurer Sir Stuart Wheeler because he believes Britain should be "free from Europe".
