The crisis of capitalism is radicalising countless young people, who are hungry for revolutionary ideas and organisation. More and more are identifying themselves as communists. The youth wing of the Communist Party of Britain, the Young Communist League (YCL) has grown on this basis. The British Marxists of Socialist Appeal issued a friendly but sharp open letter to the comrades of the YCL, showing how the opportunism of their leaders, and their emphasis on stunts over theory, stand in sharp contrast to the real ideas of Lenin. The response from the YCL’s official channels entirely proved the comrades’ point.
