Far-right surge and US revenge killings - the front pages
With voting across the rest of the continent in the European Parliament elections not closing until 22:00 on Sunday night, Monday's early editions did not have any real results to write about.
But that does not stop them commenting on UKIP's success in the UK, and the surge of the far-right elsewhere.
The Guardian says European politics was "jolted as seldom before" as "France's extreme nationalists triumphed" and the continent delivered a "huge vote of no confidence in Europe's political elite".
And, from France's National Front headquarters, the paper's Kim Wilshire reports the words of party leader Marine Le Pen: "What is happening in France signals what will happen in all European countries; the return of the nation."
The Financial Times says the storming to victory of the country's far-right National Front has displayed a surge "set to reverberate far beyond Brussels politics".
However, that success is tempered by a warning note from the Daily Telegraph, which says that despite the party's "breakthrough moment" in the European polls, UKIP is "hopeful of winning only a handful of seats" in next year's general election.
The surge in UKIP support has brought a referendum on the UK's EU membership a step closer, according to the Daily Express. The paper says Prime Minister David Cameron wants to "confront the Liberal Democrats and Labour with a dilemma".
The Express says the two parties will "have to choose whether to cave in and agree to the referendum or enrage voters by blocking the move".
But amidst Conservative concerns over UKIP's popularity, London Mayor Boris Johnson, writing in the Telegraph, says the "peasants' revolt going on" in Europe is good news for the prime minister.
The message emerging is that the EU must hand power back to the people, Mr Johnson says, and "only one government... has been campaigning solidly for the renegotiation that is needed and that is David Cameron and the Conservative-led coalition".
Gun laws debate
The killing of seven people by a Briton in California continues to feature heavily in most of the papers.
The Daily Mirror devotes its front page to the story, claiming that Elliot Rodger "blamed an innocent girl for starting his hatred of women".
And the Daily Express says he "planned to massacre 50 people, according to a manifesto he wrote, filled with hatred".
The Sun carries the views of a criminal psychologist, who suggests that the killer's final online posting "blends self-absorption, entitlement, fantasy and a lack of empathy that should have been a warning beacon".
The paper says the "heartfelt response of one bereaved father pricked America's conscience. But the right to bear arms is unlikely to be circumscribed".
And the Telegraph says that despite a relative being disturbed by the videos Rodger had posted online, it is a "sign of how deeply embedded the gun culture is in the US" that officers neither searched his apartment for weapons nor apparently asked him whether he owned guns.
'Path of destruction'
The Times carries a letter written to the paper by a senior Syrian rebel commander, who claims that the majority of fighters in the "most violent terrorist group" based in the country are British.
In his letter, Brigadier-General Abdulellah al-Basheer, a leading member of the Free Syrian Army, says while other fighters in the group come from France, Germany, Belgium and a range of countries across the Middle East, Africa and the Gulf, most are from the UK.
"They are not freedom fighters," he writes, "they are terrorists. We the Syrian people now experience beheadings, crucifixions, beatings, murders... Many who participate in these activities are British."
And he appeals to the British government to send arms to the Syrian opposition to help it deal with the "increasingly brutal threat" of the Islamic State of Iraq and the Levant (ISIL).
The rebel commander warns that a failure to act could see British extremists returning home to "continue on their pernicious path of destruction".
The Times says the warning came as MPs said a debate on policy in Syria was long overdue.
'Garden tax '
The paper claims one in three councils in England and Wales charges residents up to £120 a year to collect garden waste and says it raises fears that many householders simply send their hedge trimmings to landfill, or dump it in the street, to avoid the charge.
It cites the case of Birmingham City Council, the UK's largest local authority, which introduced a £35 charge for garden waste collection in February. The paper says just 37,000 of the city's 400,000 households have signed up for the service.
Cracking insight, Gromit
The notebooks of Wallace and Gromit creator Nick Park are "jam-packed with gems, vivid character sketches. ideas for jokes and crazy scenarios, and designs for outlandish inventions", writes the Guardian's Steven Morris.
The paper says a few pages of Park's work are to grace an exhibition, but that it was given a "deeper peek" inside the animator's notebooks.
"They offer a fascinating insight into the creative process, showing how some characters arrive unexpectedly and fully-fledged, and how others develop slowly and evolve."
And Mr Morris reveals that not it is "not only images that Park toys with in his sketchbook". Apparently Bunny Trouble, Run Rabbit Run, The Great Vegetable Plot and the Vegeburglars were all considered, then rejected, in favour of what was to become The Curse of the Were-Rabbit.
