framework of the new party was formulated at the Albury Conference. Officially launched at the Sydney Town Hall on 31 August 1945, the Menzies-led Liberal Party of Australia inherited the UAP's role as senior partner in the Coalition. Curtin died in office in 1945 and was succeeded by Ben Chifley. The reconfigured Coalition faced its first national test in the 1946 election. It won 26 of 74 seats on 45.9 percent of the two-party vote, and remained in minority in the Senate. Despite winning a seven-seat swing, the Coalition failed to make a serious dent in Labor's large majority. 1949 election campaign Over the next few years, however, the anti-communist atmosphere of the early Cold War began to erode Labor's support. In 1947, Chifley announced that he intended to nationalise Australia's private banks, arousing intense middle-class opposition which Menzies successfully exploited. In addition to campaigning against Chifley's bank nationalization proposal, Menzies successfully led the 'No' case for a referendum by the Chifley government in 1948 to extend commonwealth wartime powers to control rents and prices. In the election campaign of 1949, Menzies and his party were resolved to stamp out the communist movement and to fight in the interests of free enterprise against what they termed as Labor's 'socialistic measures'. If Menzies won office, he pledged to counter inflation, extend child endowment and end petrol rationing. With the lower house enlarged from 74 to 121 seats, the Menzies Liberal/Country Coalition won the 1949 election with 74 House seats and 51.0 percent of the two-party vote but remained in minority in the Senate. Whatever else Menzies's victory represented, his anti-communism and advocacy for free enterprise had captured a new and formidable support base in postwar Australian society. Second prime ministership After his election victory, Menzies returned to the office of Prime Minister on 19 December 1949. Cold War and national security The spectre of communism and the threat it was deemed to pose to national security became the dominant preoccupation of the new government in its first phase. Menzies introduced legislation in 1950 to ban the Communist Party, hoping that the Senate would reject it and give him a trigger for a double dissolution election, but Labor let the bill pass. It was subsequently ruled unconstitutional by the High Court. But when the Senate rejected his banking bill, he called a double dissolution election. At that election, the Coalition suffered a
