Kenyatta developed contacts with radicals to the left of the Labour Party, including several communists. In the summer of 1929, he left London and traveled by Berlin to Moscow before returning to London in October. Kenyatta was strongly influenced by his time in the Soviet Union. Back in England, he wrote three articles on the Kenyan situation for the Communist Party of Great Britain's newspapers, the "Daily Worker" and "Sunday Worker". In these, his criticism of British imperialism was far stronger than it had been in "Muĩgwithania". These communist links concerned many of Kenyatta's liberal patrons. In January, Kenyatta met with Drummond Shiels, the Under-Secretary of State for the Colonies, at the House of Commons. Kenyatta told Shiels that he was not affiliated with communist circles and was unaware of the nature of the newspaper which published his articles. Shiels advised Kenyatta to return home to promote Kikuyu involvement in the constitutional process and discourage violence and extremism.
