• Canada claim heated victory at Winter Olympics

• Both teams accuse each other of violations

Tensions boiled over as Brad Jacobs’ Canada beat Sweden 8-6 in an intense round-robin curling game on Friday, with Niklas Edin’s team alleging that their opponents were double touching the stone during the contest.

Trouble began early when the game was halted after Sweden claimed Canada’s curlers were touching the stone following release and asked officials to keep an eye out for further incidents. In response, Canada asked for the officials to do the same on Sweden’s delivery, leading to a frosty atmosphere between the teams.

NAACP alleges artificial intelligence firm is violating Clean Air Act and polluting Black communities in Mississippi

Elon Musk’s artificial intelligence company xAI is facing a second lawsuit alleging it is illegally emitting toxic pollutants from its enormous datacenters, which house its supercomputers and run the chatbot Grok.

The new pending suit alleges xAI is violating the Clean Air Act and was filed Friday by the storied civil rights group the NAACP. The group’s 40-page notice of intent to sue alleges xAI has been polluting Black communities near its facility in Southaven, Mississippi. The pollution comes from more than a dozen portable methane gas generators that xAI set up without permits, the notice alleges.

British PM to tell Munich Security Conference that Europe together is ‘sleeping giant’ and will say UK won’t turn away from its allies

Keir Starmer will say the UK and Europe need to step up their commitments to Nato and avoid the risk of overdependence on the US for defence, as he sets out one of the main planks of his foreign policy vision on Saturday.

Speaking at the Munich Security Conference, the prime minister will warn against the idea of the UK turning inwards on security, instead calling for a focus on what he will call the “sleeping giant” of shared European defence capabilities.

President insists he will also restrict mail-in voting, even if Congress fails to pass the Save America Act

Donald Trump threatened on Friday to impose a requirement that US voters present photo identification before being allowed to cast ballots in the upcoming midterm elections.

Trump insisted he will push for the change even if Congress fails to pass the Save America Act, which cleared the House earlier this week but faces an uphill battle in the Senate. The bill would impose a national photo identification requirement to vote, in addition to requiring proof of citizenship to register and drastically limiting mail-in voting.

• Defender’s current contract expires at end of the season

• ‘We wouldn’t be in talks if we didn’t want him to stay’

Arne Slot has described Ibrahima Konaté as “vital” to Liverpool and the club have not given up hope of convincing the defender to sign a new contract.

Konaté has endured a tough time on and off the pitch this season but has impressed since returning from compassionate leave against Newcastle following the death of his father. Liverpool’s central-defensive rebuild is under way with the signings of Giovanni Leoni and Jérémy Jacquet, for an initial £26m and £55m respectively, but Slot insists Konaté remains an essential part of his plans.

• Briton triumphs by nearly a second in Milano Cortina

• First British man to win individual winter gold since 1980

And on the seventh day, Great Britain finally won their first medal of these Olympics. At nine o’clock on Friday night Matt Weston, the man his teammates call “Captain 110%”, became the first British man ever to win the gold in the men’s skeleton, after four faultless races across the two days of competition.

The 28-year-old broke the track record at the Cortina Sliding Centre four times in succession, and won in a combined time of 3min 43.33sec, which was almost a full second ahead of the runner-up, Germany’s Axel Jungk. “I’ve been fortunate enough to win world championships, and European championships and other things, and this blows them all out the water,” Weston said. “I almost feel numb. I keep touching this medal to make sure it is real.”

Congressperson says US president and Marco Rubio are tearing apart transatlantic alliance

Alexandria Ocasio-Cortez has accused Donald Trump of tearing apart the transatlantic alliance with Europe and of seeking to introduce an “age of authoritarianism”, as she condemned his administration’s foreign policy in front of its allies’ top policymakers at the Munich Security Conference.

Speaking at a panel on populism on Friday, Ocasio-Cortez outlined what she called an “alternative vision” for a leftwing US foreign policy, challenging the Trump administration’s shift to the right in front an audience of US allies who have grown increasingly wary of the US’s increasingly nationalist – and militaristic – global posture.
