One of the questions on tonight’s edition of “Hard Quiz” evoked memories of a different time and the original “Big Mac”.

A question on the theme of branding asked what Scott Morrison wanted to call Deputy Prime Minister Michael McCormack, in the light of the success of his own branding as ScoMo.

The answer was “Big Mac”. It clearly didn’t take off. Last week, there was media speculation that McCormack’s leadership of The Nationals may not survive the year. David Littleproud could be deputy prime minister by Christmas. We shall see.

But the Big Mac some of us remember is Frank McManus, the Democratic Labor Party (DLP) senator from Victoria from 1956 until 1962, and again from 1965 until 1974.

Born in 1905, McManus had a career as a teacher and Education Department official, before becoming Secretary of the Victorian branch of the ALP in 1950. An anti-communist “grouper”, McManus split with the ALP and joined the group that would become the DLP. In the aftermath of the 1955 split, he won election to the Senate at the December election, taking office in July 1956.

McManus was Deputy Leader of the DLP from 1956 until 1973, finally succeeding Vince Gair, a former Labor premier of Queensland, as leader in October 1973. The double dissolution election of May 1974 saw all five DLP senators lose their seats. With the exception of the late John Madigan, who won a Senate seat at the 2010 election, before quitting and setting up his own party, the DLP has never been represented in the Commonwealth parliament since 1974.

This is one of the DLP ads from the 1974 election touting Frank McManus as “Big Mac”.
