Sir Keir Starmer’s decision to appoint former EU Commissioner Peter Mandelson as UK ambassador to Washington was widely expected to be blocked by President Donald Trump. Instead, Trump’s approval has been interpreted as a strategic move that reveals a more calculated approach than his populist image suggests.
By not blocking Mandelson, Trump protects his own nominee to the Court of St James’s, Arkansas hedge funder Warren Stephens. However, the FBI has launched a formal investigation into Mandelson’s past dealings, particularly his ties to Chinese state-owned enterprises. Dossiers compiled by the Inter-Parliamentary Alliance on China detail his high-level meetings and work with Chinese firms, raising national security concerns.
Mandelson, co-founder of Global Counsel, denies ever doing business in China. Yet the investigation serves as a warning that his activities will be closely scrutinised. If the FBI finds credible threats, Trump retains the option to make Mandelson’s position untenable, mirroring the recall of Sir Kim Darroch during Trump’s first term.
Meanwhile, Trump has secured concessions including permission to address the UK Parliament and the attendance of the Prince and Princess of Wales at a White House state dinner. Mandelson has already launched a charm offensive, admitting his past description of Trump as “reckless” was “ill-judged and wrong”.
Some diplomats view Mandelson’s direct line to the Prime Minister as an asset, but critics warn that Trump may use the ambassador to amplify his own agenda. The appointment, the second political one in nearly 50 years, underscores the delicate balance of UK-US relations.
