Morning Brief, Tuesday 21 July

US forces struck Iran for a tenth consecutive night, with American officials saying the attacks targeted military capabilities used against commercial shipping in the Strait of Hormuz. Iranian officials described the confrontation as full-scale war, while Iranian state media reported tanker explosions and US Central Command disputed that account. The strikes reached well beyond the Gulf coast, including Tabriz in the northwest, while Iran launched missiles and drones toward countries hosting American forces across the region.

The military toll also climbed. Three more US service members died in recent days, bringing American military fatalities to 17 since the conflict began in late February, and Donald Trump promised retaliation for each soldier killed. Iran’s latest official figures reported 50 dead and more than 500 wounded since fighting resumed in early July. Diplomats have not vanished: Iran spoke of indirect contacts, Pakistan kept mediating, and Marco Rubio said Washington remained open to talks, but the June ceasefire has plainly collapsed.

Oil markets translated the fighting faster than diplomats could. US petrol prices crossed $4 a gallon, Brent traded above $88 a barrel, and shipping through a strait that normally carries about one-fifth of global oil supplies faced fresh disruption. Yemen’s Houthis then threatened Saudi Red Sea exports, making even the detour look less safe. This war is no longer a distant security crisis for oil importers; it has become a pump-price problem with missiles attached.

Donald Trump signed proclamations imposing 50% tariffs on a wide range of Canadian imports, including wine, hockey sticks, cement, furniture and clothing. The order exempts energy products, potash, fish and critical minerals, but it also reaches goods that had previously enjoyed protection under the US-Mexico-Canada trade framework. The duties take effect on August 19, giving Ottawa and Washington 30 days to argue before consumers and firms start paying the bill.

The White House accused Canada of discriminatory treatment of American cars, alcohol and dairy, and invoked Section 338 of the 1930 tariff law, a blunt tool that lets a president impose duties of up to 50% without Congress. Canadian officials rejected the charge, while Ontario’s Doug Ford urged retaliation if the order goes ahead. Mark Carney called the move a unilateral breach of the continental trade pact, and trade lawyers immediately focused on whether the administration can make such a large hole in a free-trade system it once claimed to defend.

Trump also tied the dispute to wildfire smoke drifting from Canada into the American Midwest and Northeast, although the formal order leaned on trade grievances rather than air pollution. The old North American bargain rested on predictability; a 50% tariff announced by proclamation turns that predictability into another negotiable concession.

Andy Burnham took office as Britain’s prime minister and immediately promised help with the cost of living. He said the government would set out measures this week and explain how it would fund them, while a ten-year plan for Britain would follow later in the year. The tone was northern mayor meets Treasury spreadsheet: warm words for households, then a quick nod to the people who buy gilts.

Burnham reshuffled hard. Rachel Reeves left the Treasury, John Healey became chancellor, Ed Miliband moved to the Foreign Office, Yvette Cooper shifted to health, and Angela Rayner returned as housing secretary. Healey pledged to meet the fiscal rules with a buffer against uncertainty, a phrase designed less for voters than for investors watching Britain’s debt costs. The new prime minister inherits borrowing costs above those of Italy, Spain and Greece, while the tax burden is forecast to reach 37% of GDP, its highest level since 1948.

Burnham’s biography gives him political room. He ran Greater Manchester for nine years, built a brand around buses, housing and public health, and has long argued that Britain gives too much power to London. Yet national office rarely rewards mayors for sounding local once the numbers turn national. His premiership begins not with a sweeping mandate, but with a ledger, a cost-of-living promise and a very narrow permission slip from the bond market.

A federal judge in Oakland temporarily blocked Paramount Skydance from closing its $110bn acquisition of Warner Bros Discovery for at least 14 days. Araceli Martínez-Olguín also barred the companies from integrating operations, sharing sensitive information or cutting jobs while the states press their antitrust case. A hearing on August 3 will decide whether the pause becomes a longer injunction.

The lawsuit, led by California and New York with 10 other states, argues that the combined group would control roughly 27% of film distribution and more than 30% of the blockbuster segment. That would unite two of Hollywood’s five major studios with HBO, CNN, Warner’s library and Paramount+, while the Writers Guild of America warns of mass layoffs and cinema owners fear fewer films. Paramount counters that the deal would create a stronger rival to Netflix and Disney, and says the states misunderstand modern media markets.

The ruling also carries political weight because David Ellison’s family has ties to Donald Trump, and CNN staff have worried about possible editorial changes under new ownership. The Justice Department cleared the deal in June, but the states have now shown that federal approval does not end the story. Hollywood consolidation has hit an old American test: if a merger cannot be cleanly undone, courts may stop it before the credits roll.

Spain prepared for its third major heatwave of the summer as AEMET issued warnings for extreme temperatures, Saharan dust and fire danger. Seven regions activated orange alerts, including Andalusia, Aragon, Catalonia, Murcia and Valencia, while the peak is forecast for Wednesday and Thursday. Murcia city could reach 45°C, the Guadalquivir valley may hit 42°C to 44°C, and tropical nights will keep several cities from cooling below 25°C.

Across the border, a wildfire near Saint-Tropez burned 200 hectares, destroyed four homes, damaged ten more and forced 150 people to evacuate. At its height, 600 firefighters and 200 vehicles fought the blaze, backed by water-bombing aircraft and helicopters. The Var prefecture said the fire was no longer progressing by Monday midday, but crews kept working the edges because shifting winds could reignite dry woodland.

The two stories connect in the dullest, most dangerous way: heat raises health risks in cities, dries out fuel in forests and turns small sparks into public emergencies. Europe’s summer is no longer just a season to manage; it is becoming an annual stress test for hospitals, power grids, firefighters and patience.
