What does Trump's presidency mean for the UK?
Here's how Trump's presidency could reshape British politics, and what it means for the UK at large.
On Monday, Donald Trump will be inaugurated as the 47th president of the United States.
The former Apprentice star secured a landslide victory in November, ousting current president Joe Biden.
All eyes have been on Trump since the start of his incendiary first term in office, which concluded with the violent Capitol Riot protests.
Trump has been very vocal about his top priorities as returns to the Oval office. This includes imposing large levies to disincentivise international trade, ending the Ukraine war as soon as possible, as well as dramatically curbing immigration.
His decisions will not only shape the US, but will be keenly felt closer to home.
Here's how Trump's presidency could reshape British politics, and what it means for the UK at large.
Trade
Trump's 'America first' policy means that his trading focus will prioritise the US, with him levying heavy taxes on trading partners abroad to stimulate trade closer to home.
So far, Starmer has played down the threat of Trump’s sweeping plan for US tariffs, which could significantly hamper the UK's trading prospects. If Trump goes ahead, this will mean he imposes duties of up to 20% on all global imports to the US.
While this hardline stance may alienate the US's closest neighbours, Starmer seems keen to not let that happen to the UK, declaring that he wants to get around the negotiating table and strike a trade deal in the first few weeks after Trump's return.
What might put a spanner in the works, however, is the imbalance of power in the special relationship that the UK holds so dear.
"In the UK, we think of the United States and the UK as the special relationship. But for the United States, we are one of many special relationships," Dr Dafydd Townley, a Teaching Fellow in International Security, University of Portsmouth told Yahoo News.
"Roughly a fifth of UK exports go to the US, making it the US the largest single country that we export to," Katie M Pruszynski, an academic specialising in Trump and US politics at the University of Sheffield, told Yahoo News.
While our trade with the EU bloc is far greater, Pruszynski explained, this has been complicated by the ramifications of Brexit, making us more reliant on the US than we were during Trump's first term.
"I think you'll find probably some real nervousness, particularly around small, smaller businesses that do some of their trade and export to the US, largely because there's so much uncertainty about what's to come," she added.
Ultimately, Pruszynski said, US citizens will be hit first.
Nato
Trump's stance on Ukraine and the North Atlantic Treaty Organization (Nato) will be watched closely by Russia, who have long criticised the expansion of the military alliance.
Trump was a strong critic of Nato during his first term as president and has complained about US tax dollars funding European security and Nato members not spending enough.
This includes Trump calling for Nato members to pledge 5% of their GDP on military spending, which is double the current target.
Townley notes that this figure would also mean the US has to increase its spending.
"Last year, the US only spent 3.4% on defence spending on its GDP," he said.
"The majority of nations would agree, I suspect, that there needs to be more spent on defence spending.
"But countries such as the UK, where do they find that spending when they're already struggling with budget constraints as it is?" he added.
Townley said that by setting such a challenging target, Trump may be "constructing a failure" that can "justify" the US leaving the alliance.
If the US leaves, it could also drastically affect the UK's position — but perhaps not in the way we'd expect.
"Does that mean the UK will then, as one of the three nuclear powers within Nato become considerably more important, and have a greater say and leverage?" Townley said.
By extension, the US exiting Nato could also severely hamper the prospect of Ukraine winning the war.
While the outcome is still unclear, Townley the prospect of a US withdrawal is "very concerning".
Not only would that significantly reduce the amount of military aid the US provides to Ukraine, it could embolden Russia to escalate its aggression, as well as place a heavier burden on European allies to step in to support its neighbour.
Climate change
Unveiling a series of ambitious climate packages has been a point of pride for incumbent president Biden.
Part of this climate and energy legacy was the landmark $391bn (£301bn) Inflation Reduction Act, part of which invested in clean domestic energy production, creating the likes of battery factories for electric vehicle manufacturers in industrial towns.
However, Trump has warned these measures will be the first to go, with share prices for wind and solar firms slumping in the wake of his election victory.
But while Trump may want to exact his revenge after losing one election to Biden, Townley thinks it would be a "political minefield" for him to roll back the programme.
"Biden's green energy programmes, especially for companies in Republican-controlled states, have proved to be exceptionally popular," Townley said.
"I think that he would be very foolish to withdraw entirely the support for the green policies that Biden has initiated."
Like the US, Townley said the UK is reneging on its commitments to reduce its carbon footprint.
"This government, like the previous government, keeps stepping back on its commitments to zero carbon. And so I think that we need to look at not just the United States, but a global picture," he added.
Immigration
One of Trump's key immigration pledges is to deport undocumented migrants en masse from the US.
This highly controversial stance follows on from Trump's concerted efforts in his first term to strengthen the US–Mexico border.
"I think the advent of the Trump era emboldened the conversation around immigration in the UK," Pruszynski said. "There was a very sinister dehumanisation of immigrants in the US.
"It's been a more moderate discourse in the UK, but we are talking about immigration in a new way, in a much darker way."
"Had this been a Kemi Badenoch government or, dare I say it, a Nigel Farage government rather than a Keir Starmer government, we may well see some of the echoes of US immigration policy," Townley said.
"But I think Starmer has to maintain that balance of freedom of movement but at the same time strong borders.
While, in the US in particular, we'll see an increase in border patrol spending, I don't think they've got the infrastructure to carry out mass deportations — and neither does the UK."
While Trump has had the benefit of cherrypicking sympathetic advisors and politicians, there is some "divergence between members" on his stance on immigration — including from one of his most notorious backers and head of the newly coined department of government efficiency, Elon Musk.
"Musk has been very supportive of H1B visas for those who work in electronics companies, whereas those more MAGA-orientated have said, no, we want to reduce not just illegal immigration but immigration per se into this country," Townley said.
Musk's vocal interventions in UK political issues have been noted in recent weeks, including him stoking fires around the grooming gangs scandal, a highly emotive issue heavily linked to the conversation around immigration.
Additionally, billionaire Musk has made waves by suggesting he will donate money to Nigel Farage's party, Reform UK.
Pruszynski described this pledge as "concerning".
"If we want to ensure that corporate money or people's enormous personal wealth can't tip the scales in the UK, then Keir Starmer really needs to urgently look at the rules governing donations to political parties and political candidates in the UK," she added.
Chagos Islands
Trump's influence on the UK's Chagos Islands deal has also made the headlines over the past week.
The islands are of international interest because the UK and US share a military base in the area, and the government has confirmed that Trump will be consulted on the UK’s deal to hand over the Chagos Islands to Mauritius.
Townley said that Starmer's decision to involve Trump is "indicative" that "the UK is the junior partner" in the US and UK special relationship.
"We would consider them before we make a final decision," Townley said. "I think it's a wise move on Starmer to delay it, and not to start off his relationship with Trump on a bad footing.
"The funny thing is, this deal to return the Chagos Islands to Mauritius was effectively done and dusted," Pruszynski said.
"This is part and parcel of this picture of Trump throwing his weight around on the international scene."
