William John Davies was a Welsh trade union leader.
[3][4] In June 1925 (16th, 17th & 18th), for the United Kingdom Pilot's conference held in Swansea by the United Kingdom Pilot's Association, Davies (as new vice-president of the pilot's association) along with Captain Harris and Cape Horner Captain Richard Phelps Gough were chiefly responsible as members of the Reception Committee[5][6] Davies stood to become general secretary of the NUS in December 1926, with the backing of union president Havelock Wilson.
He decided to allow an injunction to stop its activity until a special general meeting was held.
Wilson was angry at this, believing it was part of a plot by Joe Cotter to take over the union.
In September, Davies instead resigned as general secretary, and was soon expelled from the union.
