Trump-Greenland latest: Trump lashes out at European leaders in astonishing late-night Truth Social spree

European Union's foreign policy chief said the bloc will hold its ground on Greenland despite growing U.S. pressure.

Kaja Kallas stressed that tariffs threatened by Donald Trump on goods from Europe would undermine the prosperity of both the EU and the U.S.

Addressing the European Parliament, Kallas said Greenland's geostrategic importance has increased recently, stressing the NATO alliance was well-suited to deal with the security of the island.

The governor of the Bank of England has warned Britain’s economists must “be very alert” to the financial impact of Donald Trump’s geopolitical approach.

Andrew Bailey told MPs at Parliament’s Treasury Committee that the “level of geopolitical uncertainty and geopolitical issues is a big consideration”.

“Let me put that in a bit of context in two respects. One, having said that, growth in the world economy was a lot more stable than we thought it would be,” he explained.

“The second point is about financial markets and is a fairly similar point, that we worry considerably about how markets react to those things.

“Market reactions have actually been more muted than we would have feared and expected. Overriding those points, I take neither of those as a point of assurance. We have to be very alert to these things.”

Denmark can't negotiate on sovereignty, identity, borders and democracy, Prime Minister Mette Frederiksen told parliament, resisting pressure as the United States levies threats of tariffs against its backers over Greenland.

Frederiksen warned that the worst “may still be ahead of us” as he vowed to respond to any threat of a trade war.

EU leaders will discuss their options for responding to Trump’s threat of tariffs at an emergency summit in Brussels on Thursday.

One option is a package of tariffs on 93 billion euros ($108 billion) of US imports that could automatically kick in on 6 February after a six-month suspension.

Another option is the "Anti-Coercion Instrument" (ACI), which has never yet been used and which could limit access to public tenders, investments or banking activity or restrict trade in services.

The EU said it was continuing to engage "at all levels" with the US but said the use of its ACI was not off the table.

British Prime Minister Keir Starmer called for calm discussion between the allies, adding he did not believe Trump was considering military action to seize Greenland.

The UK should consider expelling American troops from British bases, according to Green leader Zack Polanski, as he called for the nation to leave the Nato military alliance.

Polanski told the Guardian: “I think it’s pretty worrying that we’ve allowed ourselves to become so reliant on American interests, and that a lot of this depends on if Donald Trump is in a good mood or not.”

He said: “We should be reviewing US bases on UK soil, and actually looking at a genuine strategic defence review.”

He said that he did not believe that Nato could be reformed from within, given Trump’s “domination” within the bloc.

Political editor David Maddox was in the Oval Office when Trump gave his blessing to Starmer for the Chagos deal, but now the US president has changed his mind as the row over Greenland spirals out of control:

Republican Mike Johnson, the speaker of the US House of Representatives, did not mention Greenland as he gave a speech to MPs and peers to mark the 250th anniversary of American independence.

But he did not back away from the US’s stance either, encouraging the UK to work together with his country and warning a “strong” America was in everyone’s interest.

Although he said he wanted to “calm” waters, just a few hours after Trump launched a shock attack on Keir Starmer’s government, his words will be of little comfort to the prime minister.

As US speaker Mike Johnson addressed parliament in Britain, carefully stepping around the Greenland issue, Russia’s veteran foreign minister told reporters that Nato’s unity was now in question over the fate of the territory.

"Crisis trends are building within Western society itself. Greenland is a clear example, the one on everyone's lips,” he said on Tuesday.

“It was difficult to imagine such a thing happening before, including the prospects for Nato to remain a unified Western military-political bloc.”

Lavrov also said that Greenland was not "a natural part" of Denmark and that the problem of former colonial territories was becoming more acute.

He added that Russia had no interest in interfering in Greenland's affairs and that Washington knew that Moscow itself had no plans to take control of the island.

Keir Starmer had earned a reputation as "the Trump whisperer" internationally but the US president's words on the Chagos islands suggest that things are going wrong.

When they first met after the inauguration in February last year, it appeared that Sir Keir could get whatever he wanted from Donald Trump - a trade deal, agreement on Chagos and the UK/ US Diego Garcia airbase, and more.

Now the president has decided the Chagos deal was "completely stupid" as the row over his desire to cede Greenland from Denmark escalated.

Trump has not taken the UK's support for Denmark well at all and the threat of tariffs now seems to be a first step in a relationship that is completely unraveling leaving the prime minister badly exposed.

US House Speaker Mike Johnson added that he was confident that Britain and the US could work through their difference and maintain the so-called ‘special relationship’ between the two countries.

"We've always been able to work through our differences calmly as friends. We will continue to do that. I want to assure you this morning that that is still the case," Johnson told lawmakers in the British parliament.

He reiterated the importance of working together on security, maintaining “strategic strongholds around the world” and “renewing” foundational principles - again, without referencing Greenland by name.

“Our special relationship has always proven much more powerful and enduring than the enemies we face,” he says, while warning that prosperity will endure “only as long as we reject decline and recommit to our foundations”.

“With the right choices and the right leadership, we can chart our renewal,” he says.

The US continues to threaten Britain and European allies with tariffs for backing Denmark over Greenland.
