United Kingdom in September 2026: the most important developments in security
In September 2026 the United Kingdom's security news was dominated by an incident at RAF Fairford, an air base used by US forces. On September 27 police declared a major incident near the base, evacuated nearby homes and arrested several men on suspicion of explosives offences. By September 28 five British nationals were being questioned over a suspected bomb plot, and investigators were examining a possible link to Iran, which denied any involvement. US Secretary of State Marco Rubio said a foreign actor was involved, Donald Trump criticised the release of the five men on bail, and UK police said no explosive devices were found in the probe. On September 30 Andy Burnham said there were "strong indications" Iran was involved.
Iran featured elsewhere as well. Police arrested two people on suspicion of National Security Act offences relating to Iran, and a US-UK advisory warned of Iranian spyware targeting dissidents. On September 21 Burnham approved a Saudi request for military help against the Houthis, and the UK provided air-to-air refuelling for Saudi jets, flying from Akrotiri. MI5 chief said on September 11 the UK faced more threats than in the period after the 2001 attacks. On September 30 MI5 warned universities about Chinese espionage, saying more than 100 academics with links to Britain had worked on spy technology for China.
Russia and Ukraine formed another strand. A Russian drone struck a train in Ukraine on September 13 shortly after Boris Johnson had left it. A British service member, named as Major Paul Wilks, died in a road crash in Ukraine on September 14. Russian officials threatened the UK with nuclear weapons, including a report naming 23 British towns and cities, and the Russian embassy repeated the threat on September 29. Britain pledged its nuclear deterrent to the defence of the Baltic, and the army cancelled some training because of budget limits.
Domestic security cases continued. A wave of antisemitic attacks, including fireworks thrown at a London synagogue, left London's Jewish community on edge, and police arrested two people over a suspected plot against the Manchester Jewish community. Channel crossings reached more than 780 arrivals in one day on September 24. The UK launched its first military space squadron on September 23, and a Hawk jet crashed in Wales the next day with the crew ejecting safely. The last UK and US troops left Iraq at the end of the month.
