Sackville, Lionel Sackville-West, 2d Baron, 1827–1908, British diplomat. He served in numerous diplomatic posts before being appointed (1881) ambassador to the United States. He helped to settle (1887–88) the quarrel between the United States and Canada over fishing rights in the North Atlantic. In 1888 he was tricked, by a letter falsely purporting to come from a nonpolitical source, into making a statement implying that the reelection of Grover Cleveland would be to the British interest. His reply was publicized to further the Republican campaign for Benjamin Harrison. He was recalled (1888) to London upon President Cleveland's demand. He succeeded to his brother's title in 1888 and retired the following year.
