After Labor's landslide victory, Hawke was sworn in as Prime Minister by the Governor-General on 11 March 1983. The style of the Hawke Government were deliberately distinct from the Whitlam Government, the most recent Labor Government that preceded it. Rather than immediately initiating multiple extensive reform programs as Whitlam had, Hawke announced that Malcolm Fraser's pre-election concealment of the budget deficit meant that many of Labor's election commitments would have to be deferred. As part of his internal reforms package, Hawke divided the government into two tiers, with only the most senior ministers sitting in the Cabinet. The Labor caucus was still given the authority to determine who would make up the Ministry, but this move gave Hawke unprecedented powers to empower individual ministers.
