According to reports from The Guardian and other outlets, the US Department of Justice is allegedly blocking a Metropolitan Police investigation into former UK minister Peter Mandelson. The reports suggest the DOJ has refused to cooperate with UK authorities, citing unspecified reasons, which has stalled the probe.
Peter Mandelson, a prominent Labour figure, has not been formally charged, and the nature of the investigation remains unclear. The Metropolitan Police have declined to comment on ongoing inquiries, while the US DOJ has not issued a public statement.
This development has raised questions about transatlantic legal cooperation, with some UK officials expressing concern over the lack of transparency. No official confirmation has been provided by either government as of April 24, 2026.
