The Working Men's Club and Institute Union (CIU or C&IU) is a voluntary association of private members' clubs in Great Britain & Northern Ireland, with about 1,800 associate clubs. One club in the Republic of Ireland, the City of Dublin Working Men's Club is also affiliated. Most social clubs are affiliated to the CIU. They do not have to be working men's clubs, although most are. There are many village clubs, Royal British Legions, Labour Clubs, Liberal Clubs, and various other clubs involved. A member of one CIU-affiliated club is entitled to use the facilities of all other CIU clubs, although they will only be entitled to vote in committee elections in clubs where they are full members. The CIU has two main purposes: to provide a voice at national level for working men's clubs and social clubs, and to provide discounted products and services for its members. (en)
