Russia Dominates UK Security Debate Amid Vetting Scandal

The day opened with a security embarrassment. The Guardian reported that UK Security Vetting had recommended denying Peter Mandelson clearance to become ambassador to the US, flagging his ties to China's finance minister Lan Fo'an, the sanctioned Russian oligarch Oleg Deripaska and a former Israeli intelligence general, Tamir Hayman, along with a £1m loan for an Israeli startup and a potentially compromising relationship. Foreign Office permanent secretary Olly Robbins overrode the recommendation as "borderline." Emily Thornberry, the Labour chair of the foreign affairs committee, said that account was now "pretty incredible"; Iain Duncan Smith asked "what in hell was so important about him" that the prime minister sent him to Washington; and Ed Davey called the government's continued withholding of the vetting summary an "utter disgrace."

Russia ran through the rest of the security agenda. In her first public speech, GCHQ director Anne Keast-Butler said nearly 500,000 Russian soldiers had been killed since the 2022 invasion of Ukraine and warned the UK was at a "moment of consequence," with Moscow "relentlessly" targeting critical infrastructure, supply chains and public trust through an undeclared hybrid war on Britain and NATO; she urged businesses and the public to harden their cyber defences. At the Riga Drone Summit, UK Armed Forces Minister Al Carns argued NATO must restructure itself around drones rather than bolt them onto existing forces, citing 12,000 drones aloft during one 24-hour battle and Russia's issuing of a million drones to the front over December and January, and pointing to Britain's £600m in drones sent to Ukraine in 2024, a scale-up from 10,000 to 100,000 units in 2025, and a £4bn investment in uncrewed systems. Britain also signed the Northolt Treaty with Poland at the Battle of Britain Bunker, where Keir Starmer hailed a "generational uplift" and Donald Tusk cited "shared values"; the pact covers medium-range air defence, joint procurement and exercises, uncrewed systems for NATO's eastern flank, countering Russian disinformation, and irregular migration.

North of the border, the SNP finances case advanced. Nicola Sturgeon's solicitor, Aamer Anwar, defended the former first minister's decision to answer "no comment" during her 2023 police interview as standard legal advice, after her estranged husband and former SNP chief executive Peter Murrell pleaded guilty on Monday to embezzling more than £400,000 from the party over 12 years. Anwar said Sturgeon had since given a detailed written response and had no knowledge that party funds were spent on personal items.

The weather supplied the day's other emergency. A record May heatwave driven by a heat dome pushed UK temperatures past 35C and French highs above 39C, both setting new monthly records on consecutive days. UN climate chief Simon Stiell called the event a "brutal reminder" of the climate crisis and blamed the burning of coal, oil and gas; at least seven heat-related deaths were reported in France, while Spain, Italy and Germany imposed heat alerts and work restrictions.
