Frederick Leverton Harris (17 December 1864 – 14 November 1926)[1] was a British businessman and Conservative Party politician. He sat in the House of Commons for three periods between 1900 and 1918.
His role in Parliament was largely insignificant until World War I, when he used his knowledge of shipping to play a crucial role in the United Kingdom's economic warfare against the German Empire, and joined the government in 1916 in a newly created post with specific responsibility for the blockade of Germany. As the war drew to a close, his political career looked set to flourish, but was destroyed by scandal.
