Gaitskellism
Wilson went on to become Prime Minister in the 1964 election, holding the position from 1964 to 1970 and from 1974 to 1976. Despite being a former Bevanite, Wilson largely followed Gaitskellite economic policies, and the former Gaitskellite Callaghan followed Wilson as Prime Minister from 1976 to 1979 and Party Leader from 1976 to 1980.
Chris Watson
Watson's term as Prime Minister was brief – only four months, between 27 April and 18 August 1904. The Watson Government did pass a handful of bills, but more importantly it set the precedent of a Labour Party Prime Minister. He resigned as Labour leader in 1907 and from Parliament in 1910. Labour led by Andrew Fisher would go on to win the 1910 federal election with over 50% of the primary vote, representing a number of firsts: it was Australia's first elected federal majority government; Australia's first elected Senate majority; the world's first Labour Party majority government at a national level; and after the 1904 Watson minority government, the world's second Labour Party government at a national level.
