In February 1973, the Attorney-General, Senator Lionel Murphy, led a police raid on the Melbourne office of the Australian Security Intelligence Organisation, which was under his ministerial responsibility. Murphy believed that ASIO might have files relating to domestic Croatian terrorist threats against Yugoslav Prime Minister Džemal Bijedić, who was about to visit Australia, and feared ASIO might conceal or destroy them. The Opposition attacked the Government over the raid, terming Murphy a "loose cannon". A Senate investigation of the incident was cut short when Parliament dissolved in 1974. According to journalist and author Wallace Brown, the controversy over the raid continued to dog the Whitlam government throughout its term because the incident was "so silly".
