Sir Keir Starmer is about to address the nation after Donald Trump vowed to impose tariffs on the UK over its stance on Greenland.

The Prime Minister called a last-minute press conference for 9.15am today in Downing Street after speaking with the US president over the phone on Sunday.

Trump announced last week that he would place 10% tariffs on the UK, increased to 25% from June 1, until a deal is reached for Washington to purchase Greenland from Denmark.

He said the same would apply to Denmark, NorwaySweden, FranceGermany, the Netherlands and Finland.

Greenlandic, Danish and other European leaders are hoping they can still avert an intervention by the United States to forcefully acquire the island as U.S. President Donald Trump continues to insist the U.S. must have Greenland, suggesting even by military means if necessary.

In a phone call with Trump yesterday, Downing Street said the Prime Minister reiterated his belief that Greenland’s future was for Denmark and Greenland to decide.

He also stressed that the security in the High North is a priority for all Nato allies.

Sir Keir also held calls on Sunday with Danish prime minister Mette Frederiksen, European Commission president Ursula von der Leyen and Nato chief Mark Rutte.

In a joint statement warning about the potential impact of such a move, theeight affected NATO countries warned Trump’s actions could create a ‘dangerous downward spiral’.

They said: ‘We stand in full solidarity with the Kingdom of Denmark and the people of Greenland.

‘Building on the process begun last week, we stand ready to engage in a dialogue based on the principles of sovereignty and territorial integrity that we stand firmly behind.

‘Tariff threats undermine transatlantic relations and risk a dangerous downward spiral.’

The statement also pushes back against Trump’s claim that a small, newly announced joint exercise in Greenland means the Nato allies are ‘playing a very dangerous game’.

It says: ‘As members of NATO, we are committed to strengthening Arctic security as a shared transatlantic interest.

‘The pre-coordinated Danish exercise “Arctic Endurance“ conducted with Allies, responds to this necessity. It poses no threat to anyone.’

Greenland’s mass protest

Greenlanders held a mass protest on Saturday, declaring their home is ‘not for sale’.

A huge crowd of angry locals held signs and waved their national flag in the capital Nuuk.

The US President has long declared his intention to seize the mineral-rich self-governing Danish territory, saying the region is crucial for US national security.

Trump ratcheted up the language on Saturday, writing on his Truth Social page: ‘We have subsidized Denmark, and all of the Countries of the European Union, and others, for many years by not charging them Tariffs, or any other forms of remuneration.

‘Now, after Centuries, it is time for Denmark to give back — World Peace is at stake!’

Despite Trump’s pesterings, Denmark and other European leaders have repeatedly stressed that the sparsely populated island is not for sale.

Danish Prime Minister Mette Frederiksen has warned any military attack on Greenland – which Trump has refused to rule out – could spell the end of Nato.
