In the interview, the US president said Britain had "bad immigration policies and bad energy policies", that the country is "being invaded", and that it "can't succeed" with its current approach.
He also said he is looking forward to welcoming King Charles and Queen Camilla to the White House, and insisted his strained relationship with Prime Minister Sir Keir Starmer would not affect the visit.

Mr Trump told US correspondent Mark Stone that the five-minute call should not be broadcast, but said Sky News could quote him.
Read the full transcript of their conversation here:
STONE: King Charles is coming, and we now have the details of the visit. I'm wondering how you're feeling about that.
TRUMP: Great. He's a great gentleman, a friend of mine. He's a fantastic person.
STONE: And which part of it are you looking forward to the most?
TRUMP: All of it. Just being with him. I've known him for a long time. He's wonderful. Wonderful person.
STONE: Do you think, sir, that your language about Sir Keir Starmer, the prime minister, makes it a bit awkward for the British government, that you're clearly frustrated with the prime minister and he's sending the King over here.
TRUMP: Well, no, I don't. I think that I like Starmer, but I think he's made a tragic mistake in closing the North Sea oil. You see, your energy prices are the highest in the world. And I think he's made a tragic mistake on immigration.
STONE: How would you describe the special relationship right now, sir?
TRUMP: With who?
STONE: With the UK…
TRUMP: Well, when we needed them…
STONE: It's always been known as the special relationship…
TRUMP: That's right.
STONE: …I think it was the Queen, the late Queen, who first sort of coined that…
TRUMP: She and I were great friends.
STONE: …with Winston Churchill.
TRUMP: She was fabulous. How is the relationship? It's the relationship where: when we asked them for help, they were not there. When we needed them, they were not there. When we didn't need them, they were not there. And they still aren't there.
STONE: It sounds like it's very bad. In that case.
TRUMP: Well, it's been better, but it's sad. And we gave them a good trade deal. Better than I had to. Which can always be changed. But we gave them a trade deal that was very good because they're having a lot of problems. Energy is causing them problems because, think of it, they won't use the North Sea, and yet they buy a lot of their energy from Norway, which uses the North Sea, and they pay double the price. What's going on there? See, I love that country. I love your country and I would love to see it succeed. But if you have bad immigration policies and bad energy policies, you have the worst of both. You can't succeed, not possible.
STONE: But the prime minister might say it's up to him to deal with his own immigration policies and not necessarily for the president of the United States.

TRUMP: Well it is. But a lot of people ask me what I think about them, and I think they're insane. They're destroying… your country is being invaded.
STONE: By who?
TRUMP: By illegal immigrants from all over the world, including those from prisons, drug dealers, people from mental institutions. Your country is being invaded.
STONE: You know, sir, a lot of people might say that's fake news. And actually it's not, and maybe your information is not entirely accurate on immigration in the UK.
TRUMP: I've been very accurate here. We closed our border, we have nobody coming in, and we're getting rid of the bad ones that were sent in. We had some very bad ones - murderers. We had 11,888 murderers and most of them are gone. It's been pretty amazing what we've done.
STONE: Do you think your strained relationship with Keir Starmer, if I can call it that, will impact your relationship with the King or the visit?
TRUMP: No. Because… not at all. I've known the King for a long time, and he's not involved in that process.
STONE: But he's been asked to come here by Downing Street, by the prime minister.
TRUMP: I don't know who's asked. I mean, I didn't realise that, but if he is, that's my honour. It's my honour to have him at the White House. Listen, I have to go.
STONE: Can I ask you one more thing about Iran, sir? Do you think you'll have a deal by the time the King comes?
TRUMP: It's possible. Very possible. They're beaten up pretty bad. It's very possible.
STONE: All right, Mr President, thank you so much for your time.
TRUMP: Thank you. Thank you very much.
The 38-year-old woman was killed after her car was involved in a collision with a police vehicle in Eltham Road in October 2024. Her unborn child could also not be saved.
The Crown Prosecution Service (CPS) said it had authorised a charge of causing death by dangerous driving against Metropolitan Police PC Chris Johnson, 56, the driver of the police vehicle involved in the collision.
And former PC Danny Tomkins, 35, the driver of a second police vehicle, has been charged with dangerous driving in relation to the standard of his driving.
The pair will appear at Westminster Magistrates' Court on 28 May.
The Metropolitan Police said Johnson is attached to the Met's Taskforce. Tomkins was attached to the same unit at the time of the incident.
Acting Detective Chief Superintendent James Derham, who leads policing in Greenwich, said: "Our thoughts remain with the woman's family and friends, who continue to grieve the loss of her and her unborn child.
"This was a truly terrible and heartbreaking incident."
The charges follow an investigation by the Independent Office for Police Conduct (IOPC), which began a probe following a mandatory referral from the Met.
The IOPC referred a file to the CPS following the conclusion of the investigation in October 2025.

Axel Rudakubana's parents should be deported, says Tory leader
Malcolm McHaffie, head of the CPS's special crime division, said: "Following a thorough review of the evidence in this case, we have authorised criminal charges against one current and one former police officer.
"Our prosecutors have worked to establish that there is sufficient evidence to bring this case to court and that it is in the public interest to pursue criminal proceedings."
The Ministry of Justice (MoJ) announced in November that a total of 91 prisoners were released between the start of April 2025 and the end of October 2025.
However, the number for those six months is actually 129, according to the latest available data, with a further 50 inmates freed by mistake since then, the independent report by Dame Lynne Owens said.
The MoJ said releases "in error" can include misplaced warrants for imprisonment or remand, sentence miscalculations, or the result of mistakes by courts or other authorities.
It added: "If the person released is not aware of the error and makes no attempt to evade arrest, then they have committed no additional offence and in that sense, they may not be at fault.
"If it is believed that the situation was manipulated by the prisoner, for example by taking the identity of another person, then this will be classified as an escape, and not a release in error."
'Broken system' blamed
Responding to the report, published on Wednesday, Justice Secretary David Lammy called the figure "unacceptable", blaming a "broken system caused by 14 years of underinvestment and overcrowding in our prisons and courts".
Such a system "cannot be fixed overnight", he warned, while saying his department is "rolling out biometrics, a new Justice ID and up to £82m to bear down on these errors and keep the public safe after years of chaos.
He added: "Twenty million pounds of this will be used this year to digitise the archaic paper-based processes we inherited, as well as putting in more checks and more staff in place to stop these mistakes before they happen."
As well as creating digital identities for prisoners, ministers are planning to use fingerprints and facial scans to reduce the number of mistakes.
Shadow justice secretary Nick Timothy criticised Mr Lammy, saying: "David Lammy has finally admitted it - 179 prisoners let out by mistake last year, 441 in total under Labour - the highest two years on record. For months he hid the numbers, and now he's buried them in a written statement.
"What happened to the 'strongest ever checks'?"
Manhunt for migrant sex offender Hadush Kebatu
Pressure mounted on Mr Lammy last year following a series of high-profile manhunts, most notably for migrant sex offender Hadush Kebatu.
The Ethiopian was jailed for 12 months in September after being convicted of sexually assaulting a 14-year-old girl and a woman in Epping, where he was staying, shortly after his arrival in the UK.
The case of Kebatu, who has since been deported, sparked anti-immigration protests in the Essex town, centred on The Bell Hotel, where he was staying.
Ketabu told Sky News he tried to hand himself back in to police after being wrongly released from HMP Chelmsford in October, but was ignored by officers before being recaptured following a two-day manhunt costing police £150,000.
In November, Sky's national correspondent Tom Parmenter and colleague Josh Masters helped track down Algerian Brahim Kaddour-Cherif, who spent more than a week on the run after being mistakenly released from HMP Wandsworth.
Convicted fraudster William Smith, who was also released in error by staff at the jail around the same time, turned himself in following a three-day manhunt.

William Fernandez, who was awaiting trial for sexual assault, was released from HMP Wormwood by error in March 2021. He then went on to rape a 16-year-old girl and sexually assault a young woman.
In December 2019, the prison and probation Service apologised after serial rapist Joseph McCann was freed to commit a series of sex attacks on women and children.
In July 2017, an inmate who was released from prison just months into a nine-year sentence due to a "clerical error" was arrested after weeks on the run.
The number of blunders had fallen compared to the previous year, the government said.

Staff were told of the news of redundancies during an all-staff call at 3pm on Wednesday but were not given details of who would be affected.
The cuts would mark the biggest round of job cuts at the BBC in almost 15 years.
They come as the broadcaster attempts to reduce costs by 10% over the next three years.
In February, it was revealed it aimed to reduce spending by hundreds of millions of pounds within this timeframe as it continues to face "substantial financial pressures".
The latest cuts, initially reported by the Financial Times, come as former Google boss, Matt Brittin, prepares to take over as director-general next month.
The BBC also recently revealed plans to drastically reduce the team behind the coverage of national occasions such as royal and state events.
Interim director-general Rhodri Talfan Davies, who led the all-staff meeting and will head the corporation until Mr Brittin takes over on 18 May, told staff the corporation needs to save an additional £500m over the next two years.
He said: "All of this needs to be done with real care - for our audiences and, of course, for all of you.
"I know this is challenging news, and we'll need to work closely together to build our plans.
"My commitment to you is that we'll do everything possible to try to reduce the strain and uncertainty that change of this kind brings."

Trump: UK 'can't succeed'
Previously, the BBC has said: "Over the last three years we have delivered more than a half a billion pounds worth of savings, much of which we've been able to reinvest into our output across the BBC."
The BBC is predominantly funded through the annual licence fee, which rose to £180 per year on 1 April.
Philippa Childs, head of broadcasting union Bectu, said: "Cuts of this magnitude will be devastating for the workforce and to the BBC as a whole.
"BBC staff are already under significant pressure after previous redundancies. This will also inevitably impact the wider creative industries ecosystem, given the BBC's crucial anchor role in commissioning content and nurturing talent.
"At a time of fake news and an industry that is becoming more concentrated in the hands of a few multinational corporations, the UK needs a confident, ambitious and sustainably-funded BBC more than ever.
"The government must ensure that Charter Renewal puts the BBC's funding on a more secure, long-term pathway and prevent our national broadcaster facing death by a thousand cuts."
Sky News has approached the BBC for a response.
The incident in Finchley is being treated as an antisemitic hate crime, police said.
Two suspects, who were wearing dark clothing and balaclavas, approached the synagogue in Fallow Court Avenue shortly after midnight on Wednesday and threw two bottles, suspected to contain petrol, and a brick at the building.
Neither bottle ignited and no damage was reported. There were no injuries.
The matter was reported by staff to police at 8.30am.
Detective Chief Superintendent Luke Williams said: "We are aware of the significant concern that this incident will cause in the community, particularly in the wake of the arson attack in Golders Green last month.
"We are working with the affected synagogue and continuing to meet with community leaders.
"I would like to reassure the community that we take incidents of this nature extremely seriously and detectives are working urgently to identify the suspects."
He also urged any witnesses or people with CCTV or dashcam footage to contact police.
The latest incident comes after an arson attack on Jewish volunteer ambulances in Golders Green last month.
Finchley Reform Synagogue senior clergy Cantor Zoe Jacobs said the incident was "clearly an attempt to intimidate the British Jewish community, but we will not be deterred by these cowardly acts".
"Instead, we will continue to prioritise building bridges across the wider Barnet community," she said.
In a statement, the FRS said: "We are extremely grateful that nobody was hurt and that our building is also unharmed, but we know that the emotional and psychological impact of today's events is significant."
Rabbi Charley Baginsky and Rabbi Josh Levy, who co-lead the Movement for Progressive Judaism, said: "This incident is part of a wider rise in antisemitism that is affecting Jewish communities across the country.
'Almighty bang'
The road approaching the synagogue was cordoned off by police on Wednesday afternoon, and officers could be seen patrolling the street.
A forensics officer could be seen inspecting a green-topped wine bottle with a blue rag in the top outside the synagogue.
Franco Di Landro, 56, who lives close to the synagogue, said he heard an "almighty bang".
"It felt, sounded like a boulder had hit the floor, and it came from outside. I came outside but I couldn't see nothing," he said.
Mayor of London Sadiq Khan said: "I'm grateful to the Met Police for their swift response to the appalling attempted arson attack at Finchley Reform Synagogue overnight.
"The incident is being treated as an antisemitic hate crime, and there is an increased police presence in place in the local area."

Labour MP for Finchley and Golders Green Sarah Sackman said such attacks could not be allowed to become the "new normal" in Britain.
"British Jews must be free to go about their lives without fear - whether taking their children to nursery or attending synagogue," she said.
"We do not want to live behind ever higher walls."
In a letter handed out to residents, Ms Sackman added: "I understand this will be concerning to local residents. I want to reassure you that there is a strong police presence and investigations are ongoing."
The Community Security Trust (CST), which monitors antisemitism and provides protection for Jewish communities in the UK, said it was aware of the incident.
"We are supporting the affected location and are working closely with the police as they investigate and seek to identify those responsible," the CST said.
No arrests have yet been made.
