(The formal name Australian Labour Party was adopted in 1908, with the American spelling of Labor adopted from 1912.)
While it is standard practice in Australian English to spell the word labour with a u, the Party has spelt it without since Labor cabinet minister King O’MalleyKing thought he would "modernise" the name. At the time, it seemed likely that Australia would move to American spellings
King O’MalleyKing Should have read King O'Malley
Cant proof read!!
