The Marconi scandal of 1912–13 brought issues of anti-Semitism into the political mainstream. Senior ministers in the Liberal government had secretly profited from advanced knowledge of deals regarding wireless telegraphy, and critics regarded it as relevant that some of the key players were Jewish. According to historian Todd Endelman, who identified Chesterton as among the most vocal critics, "The Jew-baiting at the time of the Boer War and the Marconi scandal was linked to a broader protest, mounted in the main by the Radical wing of the Liberal Party, against the growing visibility of successful businessmen in national life and their challenge to what were seen as traditional English values."
