Liberal politics
Layton stood unsuccessfully for parliament three times as a Liberal. He fought Burnley in 1922, Cardiff South in 1923 and in 1929 he switched again to fight the London University seat. However, Layton's importance in Liberal politics had much more to do with his work at the News Chronicle and The Economist where he became a prominent member of a group of Liberals who had a major influence on public opinion. Their orbits were the Whitehall and Westminster villages. They moved in Fleet Street, the City, and Oxbridge circles. Among their contemporaries were Maynard Keynes, William Beveridge, Gilbert Murray, and Seebohm Rowntree. Layton would later chair the executive committee of the Liberal Industrial Inquiry which produced the celebrated Yellow Book of 1928.
