The Petrov Affair was a Cold War spy drama in Australia in April 1954, involving the defection of Vladimir Petrov, third secretary in the Soviet embassy in Canberra. Petrov's wife, Evdokia Petrova, a Russian spy, came to the centre of the affair when she was seized by Australian Security Intelligence Organisation agents from MVD agents who were escorting her from the country. Images of Petrova as she was taken by ASIO agents and made her decision to defect became iconic in Australia in the 1950s.
