UK Deputy Prime Minister and Justice Secretary David Lammy rejected claims from the U.S. State Department that the United Kingdom employs "two-tier policing" [1].

The dispute marks a significant diplomatic tension between the UK and the Trump administration, as Washington has explicitly questioned the impartiality of British law enforcement. This friction occurs amid heightened sensitivities regarding domestic security and the rule of law.

The U.S. State Department issued the comment from Washington, D.C., suggesting that the police treatment of student Henry Nowak following his murder indicated a divided system [1, 2]. Lammy addressed the allegation during a press briefing in London, where he defended the integrity of the UK's policing standards.

"I don't recognise this caricature," Lammy said [1].

The criticism from the U.S. government has triggered a sharp reaction from other UK political factions. Liberal Democrat party leaders labeled the State Department's comments as foreign interference, and demanded that the U.S. ambassador be summoned to explain the remarks [2].

A spokesperson for the Liberal Democrats said the U.S. intervention was "flagrant foreign interference that seeks to fan the flames of division" [2].

The term "two-tier policing" generally refers to the allegation that different groups are policed differently based on their political or social affiliations. While the U.S. administration pointed to the Nowak case as evidence of this trend, the UK government maintains that law enforcement operates without such bias [1, 2].

"I don't recognise this caricature."

This diplomatic clash highlights a growing friction between the Trump administration's approach to international commentary and the UK's insistence on sovereign judicial independence. By characterizing the U.S. remarks as an attempt to 'fan the flames of division,' UK politicians are signaling that foreign critiques of domestic policing are viewed not as diplomatic observations, but as threats to internal social stability.
