In the late 1950s, in the teeth of opposition from the major trade unions, he attempted in vain to remove Clause IV of the Labour Party Constitution, which committed Labour to nationalisation of all the means of production. He did not reject public ownership altogether, but also emphasised the ethical goals of liberty, social welfare and above all equality, and argued that they could be achieved by fiscal and social policies within a mixed economy. His revisionist views, on the right wing of the Labour Party, were sometimes called Gaitskellism.
