LONDON — British police said on Friday that they had charged a 28-year-old man with preparation of acts of ⁠terrorism, including against Nigel Farage, the leader of the populist Reform UK party.

Police and prosecutors said Joshua Kerry had been charged with ⁠preparing terrorist acts ​between May ⁠2024 and July 2026.

Kerry is due to appear at London’s ⁠Westminster Magistrates’ Court on Wednesday.

“We have been ​running ⁠a hugely intensive and ‌complex investigation for some time,” Senior National Coordinator for Counter Terrorism Policing Vicki Evans ‌said in a statement.

Farage, often ‌credited with forcing a referendum on whether Britain should stay in the European Union, has ⁠been one of the most influential figures in British politics for more than a decade.

His Reform UK was leading in the polls until recently, when a combination of allegations over party funding and Andy Burnham taking ‌over as prime minister has ​eroded support.

“Having carefully reviewed the ‌evidence we have ⁠made the decision to prosecute Joshua Kerry ⁠for engaging in conduct in preparation of terrorist acts,” ‌said Frank ​Ferguson, a chief crown ‌prosecutor from the ​Crown Prosecution Service.
