The disaffiliation of the Independent Labour Party (ILP) from the Labour Pa
rty in 1932 has been characterized in ways that make the decision almost in
explicable. The dominant view can be challenged by reconstructing the diffe
ring reasons for that decision. By stressing the importance of the increasi
ngly troubled relationship between the ILP and the larger organization, and
especially the role of the dispute over the standing orders of the parliam
entary Labour Party, one strand of ILP thinking is revealed. By showing the
tensions between this and other arguments for political separation, which
stressed need for a new and revolutionary political strategy, a nuanced exp
lanation is provided for the disaffiliation decision.
