Question: The fourth Baron Derwent served in the Conservative administration of which British statesman of the Conservative Party who served as Prime Minister from October 1963 to October 1964?

The later life of Winston Churchill documents the life of the British statesman from the end of World War II and his second term as Prime Minister of the United Kingdom, until his subsequent death and funeral in 1965.  After the end of the war Churchill had to step down as Prime Minister of the United Kingdom because the Conservative Party lost the 1945 election.  For six years he was to serve as the Leader of the Opposition.  During these years Churchill continued to influence world affairs; in 1946 he gave his Iron Curtain speech which spoke of the expansionist policies of the USSR and the creation of the Eastern Bloc; Churchill also argued strongly for British independence from the European Coal and Steel Community (which he saw as a Franco-German project as Britain still had an empire).  In the General Election of 1951 Labour was defeated and Churchill became Prime Minister for a second time.  Churchill continued to lead Britain but was to suffer increasingly from health problems.  Aware that he was slowing down both physically and mentally he resigned from the Cabinet in 1955.  However he continued to sit as an MP for Woodford until he retired from politics in 1964.  Churchill died on 24 January 1965 and was granted the honour of a state funeral.  He was buried in his family plot in St Martin's Church, Bladon near to where he was born at Blenheim Palace. <SEP>  It was created in 1881 for the former Liberal Member of Parliament for Scarborough, Sir Harcourt Vanden-Bempde-Johnstone, 3rd Baronet.  His grandson, the third Baron (who succeeded his uncle the second Baron), was an author, poet and minor diplomat.  On his death in 1949 the titles passed to his younger brother, the fourth Baron. Baron Derwent, of Hackness in the North Riding of the County of York, is a title in the Peerage of the United Kingdom.  He served in the Conservative administrations of Harold Macmillan and Sir Alec Douglas-Home as Minister of State for Trade and Minister of State for Home Affairs.  s of 2010 the titles are held by his son, the fifth Baron, who succeeded in 1986. <SEP> Baron de Ramsey, of Ramsey Abbey in the County of Huntingdon, is a title in the Peerage of the United Kingdom.  It was created in 1887 for Edward Fellowes, who had previously represented Huntingdonshire in the House of Commons as a Conservative for 43 years.  His eldest son, the second Baron, sat as Member of Parliament for Huntingdonshire and Ramsey and later served as a Lord-in-Waiting (government whip in the House of Lords) from 1890 to 1892 in the Conservative administration of Lord Salisbury.  His grandson, the third Baron, was Lord Lieutenant of Huntingdonshire from 1947 to 1965 and of Huntingdon and Peterborough between 1965 and 1968.  s of 2017 the title is held by the latter's son, the fourth Baron, who succeeded in 1993. <SEP> Alexander Frederick Douglas-Home, Baron Home of the Hirsel, ( ; 2 July 1903 – 9 October 1995) was a British statesman of the Conservative Party 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 Britain's foreign secretary than on his brief premiership.
