This assessment, made on the morning of defeat, explains to some degree the Labor Party's defeat in the general election of 1955. It raises the question of whether the party, as now constituted, is in fact a working-class party. The growth of the Labor Party, the emergence of its saints and sinners, the triumph of 1945, the disaster of 1955 make up one of the truly significant political stories of the century. For Americans it is especially important. The British Labor Party is the strongest non-communist left-wing party in any of the great democracies of the West. Granted the normal shifts in political support, it will be back in power sometime within the next ten years. The government and people of the United States must regard it as a permanent part of British political life, and they will have to understand it better than they have in the past if the alliance between the United States and the United Kingdom is to prosper. The British Labor Party is the political arm of what the old-timers like to call "the movement." And it is as well to remember that not so very long ago--Winston Churchill was a young politician then and Anthony Eden was at Eton--it was a "movement" with all the emotional fervor the word implies. The men who made the Labor Party a power in the land were not cool, reasoning intellectuals (although, inevitably, these assisted) but hot-eyed radicals who combined a fierce intolerance with a willingness to suffer for their beliefs. The movement includes the Labor Party itself; the Trades Union Congress, known universally in Britain as the TUC; the Co-Operative Societies; and some minor socialist groups. The Trades Union Congress is one of the centers of power in modern Britain. We will encounter it often in this book. Here we are concerned with its old position as the starting-point for British working-class power. The first Labor Party representatives who went to the House of Commons in 1906 were supported almost entirely by members of unions. The Parliamentary Labor Party came into being as an association of the Labor members of the House of Commons. Today it includes members of the House of Lords. There was originally a much closer co-ordination between the unions and the Labor MP's than exists now. Today the TUC, although it exerts great political power both directly and indirectly, is important principally as the national focus of the trade-union movement. All the unions of any size or importance except the National Union of Teachers, the National Association of Local Government Officers, and some civil-service staff associations, are affiliated with it.
