The Australian Labour Party (ALP) closely linked its radical nationalism to qualified anti-imperialism and mounted a fierce critique of the Right. The response of the British Labour Party (BLP) was much softer, moderate and defensive. The BLP and the ALP were united by a common, strong and consistent commitment to the liberties, traditions and values of British-inspired 'popular constitutionalism'. For most of the interwar period the ALP adopted a more critical attitude to Australia's relationship with Britain and British imperialism in general than between 1900 and the outbreak of World War One. In the pre-war period, the Australian Worker's viewpoint was an exaggerated and misleading reflection of the mainstream ALP's attitudes and practices towards the British Empire. In both countries, therefore, the importance attached to the politics of loyalism is partly related to questions of place and space.
