Sir Keir Starmer has urged Britain to unite in the face of Donald Trump's threats to invade Greenland and slap tariffs on the UK and other European allies.
The Prime Minister said the dispute over Greenland, which the US president wants to take over because of its strategic Arctic location and mineral wealth, should be resolved through “calm discussion between allies” rather than military action or a trade war.
In an emergency address from Downing Street on Monday morning, Sir Keir said the crisis was a “moment for the whole country to pull together”.
He has not ruled out military action to achieve his aim of taking the territory, which is a semi-autonomous part of the Kingdom of Denmark.

"In relation to the duty of candour, we've been clear that that matters.
"What we're now trying to do is just make sure we get the balance right when it comes to the application of any principle to the security and intelligence agencies.
"Obviously, I have to focus on the national interest - my primary duty as Prime Minister, which is to keep this country safe and secure - that is the duty I hold above all other duties, and I take it really seriously, which is why we're just taking time to make sure that we get that balance absolutely right."

He said nuclear deterrent is the UK’s “foremost weapon” when it comes to “securing the safety of the United Kingdom” and “that requires us to have a good relationship with the United States”.

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

“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.

Why does Trump want to take control of Greenland?
08:20 , Frankie Lister-Fell
Donald Trump wants to annex Greenland, an autonomous territory of Denmark, due to national security fears, he said.
The president fears that if the United States doesn’t take Greenland, Russia or China will.
He wrote on his Truth Social social media site: "NATO has been telling Denmark, for 20 years, that 'you have to get the Russian threat away from Greenland'.
"Unfortunately, Denmark has been unable to do anything about it. Now it is time, and it will be done!!!"
The island, which is the largest in the world, is also in a strategic place for the US.

It is located close to Canada, meaning it’s a critical site for the US ballistic missile defence system, and it is already home to a large US military base.
The island is also rich in natural resources, particularly rare earth minerals that are needed for telecommunications. It has potential for offshore gas and oil.

“He said that security in the High North is a priority for all Nato allies in order to protect Euro-Atlantic interests.
“He also said that applying tariffs on allies for pursuing the collective security of Nato allies is wrong.”
Our position on Greenland is very clear – it is part of the Kingdom of Denmark and its future is a matter for the Greenlanders and the Danes.
