 Alexander Frederick Douglas @-@ Home , Baron Home of the Hirsel , KT , PC ( / ˈhjuːm / ; 2 July 1903 – 9 October 1995 ) was a British Conservative politician who served as Prime Minister from October 1963 to October 1964 . He is notable for being the last Prime Minister to hold office while being a member of the House of Lords , before renouncing his peerage and taking up a seat in the House of Commons for the remainder of his premiership . His reputation , however , rests more on his two spells as the UK 's foreign secretary than on his brief premiership .
