was merged into the Clothing Group. Group 13: Glass, Pottery, Chemicals, Food, Drink, Tobacco, Brushmaking and Distribution Group 13 was highly diverse. The most important unions were those involved in distribution, the National Amalgamated Union of Shop Assistants, Warehousemen and Clerks (NAUSAWC) and the National Union of Distributive and Allied Workers (NUDAW), which later merged to form the Union of Shop, Distributive and Allied Workers. In 1952, a second seat was added, and this was invariably filled by representatives of smaller unions, the largest of which were the Bakers', Food and Allied Workers' Union (BFAWU) and the National Society of Pottery Workers (NSPW). There were many smaller unions, and the Tobacco Workers' Union (TWU) secured representation for a few years.
