Keir Starmer learned the hard way that you cannot charm a populist who views international diplomacy as a personal transaction. After pulling out all the stops to burnish the special relationship—even securing that high-profile, all-smiles second state visit invitation at the Oval Office—Starmer still found his administration facing an unpredictable, often abusive dynamic from Washington. Now, as the keys to 10 Downing Street look set to change hands, Andy Burnham is on the verge of inheriting this exact diplomatic minefield.
With Starmer stepping down following a brutal wave of government resignations, Burnham has transitioned rapidly from his role as Mayor of Greater Manchester to the Member of Parliament for Makerfield. Barring any late, unforeseen challengers, he is expected to become prime minister within weeks. But the honeymoon period will not exist. Waiting for him on the other side of the Atlantic is a second-term Donald Trump who has already fired his first public salvo, labeling the incoming British leader "extremely liberal."
If Burnham wants his premiership to survive the inevitable geopolitical shocks, he has to completely abandon the traditional Downing Street playbook. Trying to match Trump's personality or pleading for the historic sanctity of the Anglo-American alliance is a guaranteed route to failure.
The Illusion of the Special Relationship
American presidents generally do not spend their time tracking the careers of British regional mayors. To the current White House, Burnham is an unknown quantity, a local politician suddenly thrust onto the global stage. Trump's worldview is entirely transactional, viewed through a lens of strength, deference, and personal loyalty. Former diplomats have long warned that the concept of a "special relationship" is largely a British fixation, not an American one. Under Trump, it behaves less like a partnership and more like an abusive cycle where British prime ministers are tested, pressured, and occasionally humiliated publicly to serve domestic US political narratives.
Burnham's past rhetoric gives the White House plenty of ammunition to test him. On the campaign trail and in past interviews, he hasn't hidden his distaste for the populist wave, explicitly warning voters against a "divided, dark politics of the kind we see in the United States." He previously argued that Trump brought global instability on par with the economic chaos unleashed by Liz Truss.
Predictably, the White House has already hit back. Officials have dismissed his critiques by blaming left-wing European policies for urban decay and unchecked migration. Trump knows exactly how to press Burnham's buttons. The incoming prime minister is famous for wearing his heart on his sleeve, an open political style that worked brilliantly when rallying voters in the North of England but acts as an exposed nerve in international diplomacy. If Trump senses that a public swipe can provoke an emotional, defensive reaction from Downing Street, he will keep hitting that button.
How to Handle a Transactional White House
So how does a incoming Labour prime minister manage an American president who openly disdains standard diplomatic norms? You treat the relationship like a cold business contract, not a family reunion.
The mistake most British leaders make is treating a US president like a conventional statesman who respects historical treaties and shared values. Instead, Burnham needs to treat Trump like a highly emotional, unpredictable domestic actor. You don't try to win a public shouting match, nor do you offer sycophantic praise in the hopes of being spared. You focus strictly on hard outcomes and shared strategic interests.
The strategy should look like this:
- Ignore the personal bait: When the inevitable late-night social media posts or press conference insults arrive from Washington, Downing Street must greet them with total silence. Reacting only validates the attack and elevates the conflict.
- Find the policy overlaps: Despite deep ideological differences on climate policy, globalism, and international institutions, both men share a core political diagnosis. Both rose to power by identifying that mainstream, highly centralized politics failed working-class communities outside the capital cities. Trump's populism and Burnham's "Manchesterism" both tap into regional economic neglect. Framing bilateral discussions around domestic manufacturing, jobs, and regional regeneration speaks a language Trump understands.
- Build congressional alliances: Burnham shouldn't put all his diplomatic eggs in the basket of the executive branch. His team needs to build deep, extensive networks with the US Congress, particularly if the political winds shift in the midterm elections. Cultivating relationships with state governors and congressional leaders offers a vital buffer when the White House becomes unmanageable.
The Looming Defence Dilemma
The first real test of this new approach won't be a speech or a summit. It will be the defense budget. Before exiting, Starmer pressed ahead with a massive upgrade to UK military spending, pledging an extra £15 billion over the next four years. This was designed as a legacy project, but it has left a massive problem on Burnham's desk: a £4.7 billion funding black hole in the immediate investment plan that wasn't fully communicated during initial civil service transition talks.
This isn't just a domestic accounting headache. It's a direct geopolitical liability. Trump has made it clear that his commitment to European security and NATO is entirely conditional on European nations paying their own way. If Burnham takes office and immediately looks like he's wavering on defense spending to fix a domestic budget crunch, Washington will notice.
Burnham has promised to honor the tight fiscal rules set out by the Treasury, ruling out increased borrowing to plug the gap. To keep the defense commitment intact and avoid giving Trump an easy excuse to side-line the UK, the new administration will have to make painful trade-offs. This means finding savings by squeezing other departmental budgets, cutting back on planned infrastructure projects, or facing down a major internal party rebellion by reforming welfare spending. It is a brutal welcome to high office, but maintaining credible defense targets is the minimum price of admission for dealing effectively with Washington.
Your Next Move
Managing international relations under a populist US presidency requires a total shift in mindset. If you are analyzing or working within modern political strategy, stop relying on old diplomatic templates.
Start building strategy around transactional realities rather than historical sentimentality. Identify where hard, material interests align—whether in trade, defense procurement, or intelligence sharing—and keep the focus exclusively on those metrics. When dealing with highly reactive external forces, absolute emotional discipline is your strongest asset. Build institutional resilience through broader legislative networks rather than risking everything on a single relationship with a volatile leader.
