Minerals and Energy Minister Rex Connor wanted funds for a series of national development projects. He proposed that to finance his plans, the government should borrow $US 4 billion (at that time a huge sum of money). It was a requirement of the Australian Constitution that non-temporary government borrowings must be through the Loan Council. Although the development projects were long-term, Whitlam, together with ministers Cairns, Murphy and Connor authorised Connor to seek the loan on 13 December 1974, without involving the Loan Council. Connor had already been investigating the loan. Through an Adelaide builder, he had been introduced to Pakistani dealer Tirath Khemlani. According to Khemlani, Connor asked for a 20-year loan with interest at 7.7% and set a commission to Khemlani of 2.5%. Despite assurance that all was in order, Khemlani began to stall on the loan, notably after he was asked to go to Zurich with officials of the Reserve Bank of Australia to prove that the funds were in the Union Bank of Switzerland as he had claimed. The government revised its authority to Connor to $2 billion.
