Economists say levies of 10-50% have dramatically added to the risk of a worldwide downturn

Global financial markets have been plunged into turmoil as Donald Trump’s escalating trade war knocked trillions of dollars off the value of the world’s biggest companies and heightened fears of a US recession.

As world leaders reacted to the US president’s “liberation day” tariff policies demolishing the international trading order, about $2tn (£1.5tn) was wiped off Wall Street and share prices in other financial centres across the globe.

In the aftermath of the disastrous debate against Donald Trump that ultimately ended his political career, Joe Biden skipped a White House meeting with the congressional Progressive caucus in favor of a Camp David photoshoot with the fashion photographer Annie Leibovitz, a new book says.

“You need to cancel that,” Ron Klain, Biden’s former chief of staff and debate prep leader, told the president, as he advocated securing the endorsement of the group of powerful progressive politicians perhaps key to his remaining the Democratic nominee.

Percy Pig’s US invasion could be called to a halt amid fears that Donald Trump’s tariffs could affect sales of Marks & Spencer’s popular confectionery brand which has just launched in Target stores across the Atlantic.

Archie Norman, the chair of M&S, has described Percy as the retailer’s “gift to America” but he told the Retail Technology Show in London that “we might have to change our minds” as Trump imposes additional taxes on imported goods. While M&S is not considering withdrawing the sweets, tariffs could push up prices and make them less popular.

The US president’s announcement has caused market chaos and threatens a trade war and US recession

Donald Trump’s announcement of a long slate of new tariffs on the US’s trading partners has caused chaos in global markets and threatens a global trade war and US recession.

Long trailed on his election campaign, Trump’s plans were even more sweeping than many had predicted: a baseline 10% tariff on all imports and higher tariffs for key trading partners, including China and the EU.

‘Willing sycophants’ came up with simplistic formula that has thrown global economy into disarray

• US politics live – latest updates

Waving a big chart as a prop in the White House Rose Garden, Donald Trump suggested his new tariff plan was simple: “Reciprocal – that means they do it to us, and we do it to them. Very simple. Can’t get simpler than that.”

Perhaps a bit too simple. The method used to calculate the most important numbers in international trade, politics and economics has left some of the world’s leading experts shocked.

Goods trade deficit: $291.9bn

Total goods imports: $438.9bn

Those figures divided = 0.67, or 67%

And halved = 34%

Reciprocal tariffs are calculated as the tariff rate necessary to balance bilateral trade deficits between the US and each of our trading partners. This calculation assumes that persistent trade deficits are due to a combination of tariff and non-tariff factors that prevent trade from balancing.

The president displayed the top of his list from a podium in the White House Rose Garden, and later published a longer version. Note that the “tariffs charged to the USA” in Trump’s formulation include “trade barriers” so don’t necessarily align with the tariffs published by countries concerned.

• Trump tariff reaction – live updates

Countries across the world are racing to absorb the new way of doing business with the US, after Donald Trump unveiled tailored tariffs that looks set to ignite a global trade war.

Trump has made clear the goals he wants to accomplish through the tariffs: bring manufacturing back to the US; respond to unfair trade policies from other countries; increase tax revenue; and incentivise crackdowns on migration and drug trafficking.

Campaigners denounce ‘cover-up of a cover-up’ as IOPC clears officers of scapegoating Liverpool supporters

A 12-year investigation into the Hillsborough disaster by the police watchdog has concluded that no senior South Yorkshire police officers were guilty of misconduct for falsely blaming misbehaviour by Liverpool supporters.

That police case was wholly rejected in 2016 by the jury at the second inquest, who determined that no behaviour of Liverpool supporters contributed to the disaster, which happened on 15 April 1989 at the FA Cup semi-final between Liverpool and Nottingham Forest at Sheffield Wednesday’s Hillsborough stadium.

Defense chief and others discussed US military operations on messaging app that included journalist

The inspector general of the Department of Defense (DOD) is launching an investigation into Pentagon secretary Pete Hegseth’s use of the encrypted messaging app Signal to discuss sensitive information about military operations in Yemen.

The probe, announced on Thursday, follows a bipartisan request from the Senate armed services committee after allegations emerged that highly precise – and most likely classified – intelligence about impending US airstrikes in Yemen, including strike timing and aircraft models, had been shared in a Signal group chat that included a journalist.
