(FILES) Britain's Prime Minister Keir Starmer (L) listens to Member of the House of Lords George Robertson (R) during a meeting at 10 Downing Street in London on July 16, 2024. Robertson, the former head of NATO, warned on April 14, 2026 that Britain's national security is "in peril", as he launched a scathing attack on Prime Minister Keir Starmer's record on defence. Robertson, an ex-defence secretary from Starmer's Labour party, was to use a speech to accuse ministers of "corrosive complacency", according to excerpts reported by the Financial Times and BBC.
