The general election, for 156 seats in the 12th Union Parliament, was the first in South African history when only voters classified as white took part. In the eleven previous general elections, the Cape Province and Natal general electoral roll had included some black (until 1938 in the Cape), Asian (until 1948) and coloured electors. The election saw the collapse of the
South African Labour Party which lost all 5 of its seats and whose vote dropped from almost 35,000 votes in 1953 to 2,670 votes in 1958. The drop in support is largely attributed to the party leader
Alex Hepple's growing outspokenness in opposition to
apartheid and his co-operation with the
African National Congress, positions which were not supported at the time by white workers who were the bulk of the Labour Party's electorate. Moreover, the party did not repeat its electoral alliance with the
United Party, and its sole two candidates in the election - Hepple and
Leo Lovell - both finished in distant third places, losing their seats to United Party candidates. A total of 24 seats were uncontested, all of which were won by the United Party.
By province The overall composition of the House, after the general election, was as below. There were boundary changes, from the delimitation of seats in the previous Parliament, so no attempt is made to identify changes. ==References==
