Guy Burgess left behind a battered leather briefcase when he fled to Moscow in 1951.
Notes on verification
Core claim (Burgess leaving a leather briefcase behind when fleeing to Moscow in 1951) is corroborated by multiple independent sources tied to MI5's 2025 National Archives exhibition. The specific 'battered' descriptor is not explicitly confirmed in sources, and one source notes there were actually two briefcases involved, adding nuance not captured in the original claim.
