Highlights

  • Wennerström spy affair: On 20 June 1963 Air Force Colonel Stig Wennerström was arrested after counter-intelligence found microfilm in his attic. He had spied for Soviet GRU for ~15 years, passing Sweden's air defence plans and Saab Draken secrets. He was later sentenced to life imprisonment.
  • Four-week vacation law: The Riksdag legislated a minimum four-week paid annual leave for all employees, placing Sweden among Europe's most generous vacation regimes and reinforcing the Social Democratic welfare model.
  • Right-hand traffic decided: On 10 May 1963 the Riksdag voted to switch traffic to the right-hand side by 1967 — overriding a 1955 referendum in which 83% had voted to keep left-hand driving.
