Andy Burnham has replaced Keir Starmer as prime minister. The new PM, who says he is “acutely conscious” of being the country’s seventh in a decade, promised voters “more breathing room” on the cost of living, and will appoint his cabinet this afternoon. Home Secretary Shabana Mahmood is expected to become chancellor, while Ed Miliband is tipped for foreign secretary. The US launched strikes on Iran for a ninth consecutive night following the deaths of at least three American troops in the Middle East. US Central Command said two service members were killed in Jordan on Friday, with a third reported missing, and another died in Iraq on Saturday. A Pentagon official told The Washington Post the US does not have enough missiles to “safely sustain” a return to all-out war with Iran. Spain were crowned winners of the World Cup last night after defeating Argentina 1-0 in extra time. Four Argentinian players were booked during the match, and several got into an undignified brawl after the final whistle. It cements Argentina’s reputation, says the BBC, as the “villains of international football”.

Andy Burnham’s “new vibe” is all very well, says Jenni Russell in The Times. What matters is whether he can take difficult decisions his party dislikes but the country needs. Chief among them is controlling immigration, which voters believe is the “most pressing issue in Britain”. Shabana Mahmood is the only leading Labour politician who has been willing to champion vital curbs, but many Labour MPs have agitated to have crucial proposals in her immigration and asylum bill dropped. If she is replaced at the Home Office, her successor may well bend to party pressure. This would be a disaster.

The problem isn’t just the historically high levels of immigration – 627,000 non-EU migrants last year alone, “fewer than a quarter to work”. It’s also the power of the courts to use the European Convention of Human Rights to allow foreign nationals to enter and remain in Britain on grounds that are clearly ludicrous. Last week, a Gazan refugee won permission to bring 18 members of her extended family to the UK, including her parents, three adult siblings and their partners, and ten nieces and nephews. Most speak no English, have nowhere to live in the UK, and are statistically likely to remain a permanent burden on the state. Yet each family will skip the queue for social housing and be eligible for welfare and then pension credit for the rest of their lives. When the government offered a settlement scheme to Afghans, one man brought 22 dependents with him. Ordinary voters – and Mahmood – understand this is madness. If Burnham wants to be anything other than another “failed, transient, forgettable PM”, he must defy his party’s instincts on migration and “take back control”.

Early last Sunday, says Tom Sharpe in The Telegraph, Iran launched its widest single-night attack of the war so far, firing ballistic missiles and drones at US facilities across the Gulf. Normally, US troops are able to “spoof” the GPS signals guiding Iranian missiles, tricking them into travelling elsewhere. But this time, many of the weapons had been upgraded to make use of a Chinese encrypted sat-nav system called BeiDou-3, forcing American troops to take the much more costly route of intercepting them with missiles of their own.

Ever since it became clear the Labour party was going to oust Keir Starmer, says Liam Halligan in The Telegraph, party strategists have been praying geopolitics would be kind to them. From early June, as a US-Iran ceasefire came into view, the oil price dropped from $95 a barrel to around $70 in early July, and with the Strait of Hormuz opening, there was talk of lower energy prices, falling inflation and the return of interest rate cuts by the Bank of England. Just weeks ago, some in Andy Burnham’s team were eyeing the Middle East (through rose-tinted spectacles) and privately crowing about a “strong economic inheritance”, and rubbing their hands as they discussed how to “spend the fresh fiscal headroom”. Well, not any more.

Since the start of July, the price of oil is up by about a fifth. The US and Iran have traded fire for nine consecutive nights; freight traffic through the Strait of Hormuz – usually the route for a fifth of the world’s oil and gas supplies – remains 90% below pre-war levels. This, and fear that Burnham will shift this “already big-spending, high-taxation Labour government” even further to the left, have sent the UK’s cost of borrowing close to an 18-year high. We now pay “far more” to access credit than any other G7 nation. Interest payments alone are the third largest government expenditure, after health and welfare, swallowing a truly jaw-dropping 80% of fresh annual borrowing. What’s terrifying is that many of the Labour MPs, trade union barons and party activists who are installing Burnham in No 10 haven’t even the most basic grasp of these facts. Our incoming prime minister says he is determined to be “unashamedly Labour”. For the rest of us, that spells “economic ruin”.

Anyone who’s ever made it all the way through an IKEA will know it can feel like a marathon, says Kyle Melnick in The Washington Post. Now, dozens of runners will actually log 26.2 miles inside the giant IKEA in Croydon, with all 80 slots in the race in December sold out within a month. Competitors must complete the route – 17 laps of the showroom, market hall and warehouse – within six hours so that employees can get back to work. And somewhat inevitably, organisers are looking into stocking aid stations for runners with the store’s trademark Swedish meatballs.

It’s peanut butter, says Natan Odenheimer in The New York Times, 363 kilos of which has been spread into a 270 sq ft hexagon on the floor of a museum in Rotterdam. The idea for the artwork – which is being installed at the Depot of Museum Boijmans Van Beuningen – was conceived by the beloved and eccentric Dutch artist Wim T Schippers, who died last month aged 83. Before he died, he left strict instructions for the application of the nutty paste for Pindakaasvloer, or “Peanut Butter Floor”. Museum director Sandra Kisters says to find it, visitors should just “follow the smell”.
