Despite the ALP officially adopting the spelling without a ⟨u⟩, it took decades for the official spelling to achieve widespread acceptance.[18][lower-alpha 2] According to McMullin, "the way the spelling of 'Labor Party' was consolidated had more to do with the chap who ended up being in charge of printing the federal conference report than any other reason".[22] Some sources have attributed the official choice of "Labor" to influence from King O'Malley, who was born in the United States and was reputedly an advocate of spelling reform; the spelling without a ⟨u⟩ is the standard form in American English.[23][24] It has been suggested that the adoption of the spelling without a ⟨u⟩ "signified one of the ALP's earliest attempts at modernisation", and served the purpose of differentiating the party from the Australian labour movement as a whole and distinguishing it from other British Empire labour parties. The decision to include the word "Australian" in the party's name – rather than just "Labour Party" as in the United Kingdom – has been attributed to "the greater importance of nationalism for the founders of the colonial parties".[25]
