Co-operative Party
At the start of the war, the many retail societies in the Co-op movement grew, partly because they were  very public about "anti-profiteering".  Making a large profit in war time was seen as not being patriotic or helping the country.  When conscription (men were ordered into the army) was started and food and fuel supplies restricted, the co-op societies began to suffer.  The co-ops were started by ordinary workers, but the government distribution committees and draft tribunals were usually run by members of the upper classes and gentry.  Co-ops smaller amounts of food to sell, and coop managers were often drafted, whereas business opponents were able to have even clerks declared vital for the war effort.  Co-op Societies were also made to pay "excess profits tax" even though as co-operatives they made no profits.
