Starmer’s Appointment of Mandelson as US Ambassador: A Misstep That Risks UK-US Relations

To Trump, it signals that Britain is unserious about its relationship with the US. To the British public, it looks like yet another appointment from the Blairite back catalogue. And to Brussels, it confirms the UK is still dancing to Europe’s tune, explains Claire Bullivant.

By all measures of diplomatic logic and political prudence, Keir Starmer’s decision to appoint Lord Peter Mandelson as Britain’s next ambassador to the United States is a spectacular miscalculation.

It’s as though Starmer has taken every possible concern about the UK’s future relationship with Washington and wrapped it up with a bow in the form of a peer whose name is synonymous with scandal and whose politics belong to another age.

Damaged Goods

Let’s not forget who we’re talking about. Mandelson was forced to resign not once, but twice from the Cabinet during the New Labour years. The first instance was allegedly over a dubious loan arrangement, and the second was related to a scandal involving a passport application. While Mandelson has always protested his innocence, his time in government was, to put it charitably, accident-prone.

More recently, his consulting business, Global Counsel, has raised questions about potential conflicts of interest, given its ties to global clients. Now, as he takes up the most crucial diplomatic role in Britain’s arsenal, every aspect of his business dealings will come under scrutiny — and rightly so. The United States, particularly under Donald Trump’s return to power, has no time for murky affiliations or a whiff of impropriety.

Wrong Man for the Job

Mandelson may have thrived in the heyday of Clinton and Blair, riding the wave of liberal centrism that defined the 1990s. But we are no longer in the era of backroom deals and third-way politics. A Trump White House will be dominated by conservative techno-libertarians like Elon Musk and a renewed focus on America First economics. Mandelson, with his EU-first mindset and public criticisms of Trump, is unlikely to command the respect or trust necessary to safeguard Britain’s interests.

Tensions with Trump’s Team

This appointment is already causing waves across the Atlantic. Trump insiders have called Mandelson a “moron” and a “horrible, arrogant pick.” His past comments, labelling Trump as “little short of a white nationalist and racist” and a “danger to the world,” have not been forgotten. These are not the words of a man poised to build bridges with the next occupant of the Oval Office.

Adding to the drama, Mandelson’s close association with the disgraced Jeffrey Epstein and perceived pro-China stance are bound to raise eyebrows in Washington. It’s one thing to represent British values; it’s another to walk into the lion’s den armed with a legacy of controversial remarks and dubious affiliations.

Missed Opportunities

The UK faces a critical moment. With Trump expected to push for punitive tariffs on Europe and the US and EU drifting further apart, Britain has a golden opportunity to negotiate a comprehensive free trade deal with the United States. An ambassador with a clear grasp of trade dynamics, coupled with the ability to navigate Trump’s bombastic personality, is essential.

But Mandelson’s instincts will inevitably pull Britain closer to Brussels, a position that could alienate Washington and waste this unique moment for UK diplomacy. His EU-aligned stance risks steering Starmer’s government into a no-growth, regulation-heavy alignment that offers little for British businesses or workers.

Mandelson’s First Test

If Mandelson wants to prove his critics wrong, he must act decisively. He could start by persuading Starmer to abandon the Foreign Office’s absurd plan to surrender the Chagos Islands. Here, UK and US interests are aligned, and the costly capitulation needs to be shelved.

Moreover, Mandelson must pivot away from his EU-centric trade views and focus on the immense opportunities presented by a bilateral UK-US deal. Such a strategy would not only enhance Britain’s economic prospects but also demonstrate that he can put national interest above ideological loyalty.

But what are the chances? With Mandelson’s track record, I wouldn’t hold my breath.

A Diplomatic Disaster in the Making

To be frank, Starmer’s choice of Mandelson sends the wrong message at every level. To Trump, it signals that Britain is unserious about its relationship with the US. To the British public, it looks like yet another appointment from the Blairite back catalogue. And to Brussels, it confirms the UK is still dancing to Europe’s tune.

Mandelson may be “experienced”, but experience alone isn’t enough. Charm and connections won’t win over a Trump administration that values results over rhetoric. Starmer has picked a man who will struggle to influence the President, alienate Nigel Farage — Britain’s closest link to Trump — and miss the opportunities of a dynamic US-UK partnership.

In this critical period for UK diplomacy, Britain needed a heavyweight ambassador who Trump actually likes and respects. Instead, it got Peter Mandelson. It’s a choice that Starmer will soon regret — and one that the UK can ill afford.
