A
compositor, as his father had been, Naylor was educated at a London
Board School and
Working Men's College. He became a journalist. In 1906 Naylor succeeded
C. W. Bowerman as secretary of the
London Society of Compositors. During the London printers' strike 1911, he produced the first editions under the
Daily Herald title. He also supported the separate existence, from 1912, of the
Daily Citizen. In 1915 Naylor became chairman of the
London Labour Party, holding the position to 1928. In 1921 he was elected as Member of Parliament for
Southwark South East. He lost the seat the following year but regained it, sitting 1923–1931 and 1935–1950. ==Works==
