Call Me Maybe made the singer-songwriter famous – but also confused. Who was she? Who was her music for? Fourteen years later, about to release the double album Day and Night, she finally has some answers

Carly Rae Jepsen is as bubbly as ever as she comes down for breakfast at Manhattan’s Hotel Chelsea. She’s one of those pop princesses, like Kylie Minogue, whose voice and demeanour remain unchanged whatever the situation. And she feels at home at this New York landmark where, last year, she married the musician and producer Cole MGN. That a wedding at the Chelsea would need to be kept to about 100 people was an immediate selling point. “I loved that it was smaller,” she says. “It felt big to me! I didn’t even get time with all the people that were there.”

We’re here to talk about her new album, though, which comes out 14 years after the song that made her world-famous. Born and raised in the city of Mission in British Columbia, Jepsen had come third on Canadian Idol in 2007, and then released a low-key folk album called Tug of War in 2008, before dropping Call Me Maybe four years later. It became the bestselling global single of 2012; her second album, Kiss, came out in the same year. Now, at the age of 40, she has six more studio albums under her belt. The latest, Day and Night, is her take on marriage and motherhood. And, in its own way – which is to say, a bit coy, a bit breathy – it might also be Jepsen’s horniest album to date.

Three little letters - bnb-side’s name is a play on the local b-side arts festival, but Silicon Valley colossus sees threat to global brand

In one corner is bnb-side, a six-room bed and breakfast on the Isle of Portland – a tiny wedge of limestone tied by a narrow ribbon of shingle to the Dorset coast – that was created to help secure the future of the rock’s much-loved arts festival, b-side.

On the other is Airbnb, the San Francisco-based booking colossus. The battle between them is over the three little letters they share.

Progressive politicians such as Zohran Mamdani offer answers to the bitter post-9/11 legacy of failures at home and abroad

Twenty-five years after 9/11, two pieces of journalism, describing two different phenomena in contemporary New York, tell us a great deal about a city, and indeed a world, caught between two eras. In one, New York Magazine dives into “Habibi City”, a New York where a “cultural shift is underway, led by a generation of New Yorkers coming into its own”. This new generation is labelled as originating in “SWANA” – south-west Asia and north Africa, a region that “includes countries from Palestine to Iran to Sudan”. In the other, Vanity Fair describes calls for Zohran Mamdani to not attend the 9/11 memorial ceremony as partly founded in “inchoate, emotional” impulses, that see “the city’s first Muslim mayor as a stand-in for the 19 Muslims who hijacked four planes and turned them into deadly weapons, part of the ‘them’ who attacked ‘us’.”

Together they capture what has changed over a generation, and what remains stubbornly the same. Members of a diaspora of Muslim background are indeed breaking through and accumulating, as New York Magazine says, “clout”. They are no longer simply a fixture of bodegas and halal carts, but of Saturday Night Live, upmarket dining, entertainment and politics too. Mamdani is both the expression of that cohort and the catalyst of its recognition as an emerging force. They care deeply for their local communities but also for those in Gaza and beyond.

A sharp analysis of the damage wrought by the reckless super-rich, and progressive toolkit for repairing it

The more power the radical rightwing nationalists of our age accrue, the greater the risk that their destructive brand of politics becomes normalised. We should not, for instance, regard it as normal that the man in charge of the world’s largest nuclear arsenal casually promises “a whole civilisation will die tonight”. We should not accept that history’s first trillionaire is allowed to spread racist conspiracy theories to a hitherto unimaginable extent. We should be alarmed that, here in the UK, a party tipped to lead a potential future government is trying to cruise to power in the slipstream of this international movement.

In fact, we shouldn’t just be alarmed by such developments: we should stop them and urgently repair the damage already done. But how? And what is the nature of that damage? This bold, clarifying intervention from Naomi Klein and Astra Taylor provides some of the answers. “End times fascism” is their term for a convergence of interests that can broadly be understood as a response to the climate crisis. Faced with a world coming under unprecedented strain from environmental shocks and an unequal, resource-hungry economic system, today’s reactionaries are effectively saying: bring it on.

A bloated ballroom, a six-storey military HQ, a helipad-cum-cocktail patio, a gilded angel on a giant arch honouring himself … our architecture critic deplores the decorator-in-chief’s mutilation of Washington

When you have a developer as US president, you might expect some zhooshing up of the capital. A few buildings renovated, maybe some parks replanted. But when you have a megalomaniac builder in charge, things can get out of hand. A decade ago, when Donald Trump was first elected, I asked what it might mean for the US to be led by a real estate tycoon whose career had left a trail of broken promises, angry buyers and endless lawsuits, with rules flouted, heritage trampled and the world pockmarked by a fleet of aspirational towers clad with a flimsy veneer of luxury. The answer is worse than I could have imagined.

With the air of a nightmarish Hollywood sequel, Trump 2 has seen the president’s true architectural ambitions unleashed: The Blingpire Strikes Back. As America’s self-styled decorator-in-chief, Trump has not only overseen the gilded mutilation of the White House, but embarked on the Mar-a-Lagofication of Washington DC itself, applying his gold paintbrush to statuary, daubing ponds with flaking pool liner, and brewing plans for a colossal triumphal arch – all procured in a blizzard of no-bid contracts. And, in true dodgy salesman style, this programme of bauble-building is turning out to be a high-profile decoy for deeper damage being wrought elsewhere.

Going deep underground used to offer a refuge from the pressure to be constantly connected. That’s soon to change – and I’m not happy

Rejoice! For by the end of 2026, 4G and 5G mobile coverage is expected across the whole London underground network. After months of delays and setbacks, 121 subterranean tube stations will be dragged kicking and screaming into the 21st century, joining Paris and Berlin in perma-connectivity bliss. But should we really be so happy about the rollout?

Going deep underground was once a way of escaping the incessant communications of this exhausting modern life. Emails to respond to? WhatsApp messages piling up? The tube used to be one of the last remaining bastions of resistance against the constant expectation to do. To optimise. A simpler place where you could justifiably and believably ignore messages and reply later with a “sorry, I was on the tube”.

From Elizabeth I’s backing of early voyages to royal investment in trafficking companies, generations of monarchs were central to Britain’s slave trade

Enslaved African people were seared with hot metal brands bearing the royal crown, according to research by historians who have documented the monarchy’s centuries-long involvement in Britain’s slave trade.

The Register of British Slave Traders identifies thousands of people who invested in Britain’s trafficking of enslaved Africans, including kings and queens.

Race too close to call and may take days to become clear despite early exit polls suggesting left bloc win

With most of the votes counted, Sweden’s national election remained too close to call on Sunday night, with left-wing parties holding a lead of just a single seat according to a partial tally by the election authority.

Earlier in the night, exit polls suggested that the country was on course for a brand new left-leaning government. But as the votes were counted, it was apparent it could take days for the outcome to become clear.

Price spike comes as rebel Houthis in Yemen target oil infrastructure and capture strategic island in Bab al-Mandab strait

• Business news – live updates

Oil prices have climbed above $107 a barrel after a series of drone attacks forced Saudi Arabia to close its east-west crude pipeline.

Brent crude, the international benchmark for oil prices, surged to as much as $108 a barrel at one point on Monday, later easing back to $107.7 – a 3% increase on the day.

Richard Tice says donations are legally compliant amid speculation on overseas rules proposed in Rycroft report

Reform UK’s deputy leader has declined to say when two crypto billionaires who gave a combined £72m to the party returned to the UK, as the architect of a review into overseas donations said anyone here for less than 12 months would be subject to a limit on donations.

Richard Tice said that while he was completely confident Reform had complied with all current and proposed laws on donations, he could not say when Ben Delo returned to the UK from Hong Kong, or how much time the Thailand-based Christopher Harborne spent in Britain.
