In March 1951, the Iranian parliament (the Majlis) voted to nationalise the Anglo-Iranian Oil Company (AIOC) and its holdings by passing a bill strongly backed by Mohammad Mosaddegh, who was elected Prime Minister the following April by a large majority of the parliament. The International Court of Justice was called in to settle the dispute, but a 50/50 profit-sharing arrangement, with recognition of nationalisation, was rejected by Mossadegh. Direct negotiations between the British and the Iranian government ceased, and over the course of 1951, the British ratcheted up the pressure on the Iranian government and explored the possibility of a coup against it. U.S. President Harry S. Truman was reluctant to agree, placing a much higher priority on the Korean War. Churchill's return to power and Eisenhower's presidency brought with them a policy of undermining the Mossadegh government. Both sides floated proposals unacceptable to the other, each side believing that time was on its side. Negotiations broke down, and as the blockade's political and economic costs mounted inside Iran, coup plots arose from the army and pro-British factions in the Majlis.
