James Leslie Hamilton, 4th Baron Hamilton of Dalzell (11 February 1938 – 28 September 2006) was a British Conservative Party hereditary peer. Early life Hamilton was the elder son (and second child) of John Hamilton, 3rd Baron Hamilton of Dalzell, a Lord-in-waiting to the Queen. The title was originally granted to Hamilton's great-grandfather, John Hamilton, 1st Baron Hamilton of Dalzell, who was a Liberal politician, and had been inherited by his second son, Gavin Hamilton, 2nd Baron Hamilton of Dalzell, also a Liberal politician, before passing his nephew, Hamilton's father. His mother, Rosemary Coke, was a daughter of Major Sir John Spencer Coke, son of Thomas Coke, 2nd Earl of Leicester; her maternal grandfather was Harry Lawson, 1st Viscount Burnham. His younger brother, Archie Hamilton, a former Armed Forces Minister, became a life peer in 2005, as Baron Hamilton of Epsom. Hamilton followed his mother as a Christian Scientist, and attended Claremont Fan Court School and then Eton College. He did National Service in the Coldstream Guards from 1955 to 1958. His father had been wounded while serving with the same regiment in the Second World War. Hamilton then worked in the City of London as a gilts broker. He was a member of the London Stock Exchange from 1967 to 1980. He remained in the City for only a short period, leaving when he inherited two estates from his father's cousin. He married his wife, Corinna Dixon, in 1967, and they had four sons together. He succeeded his father as Baron Hamilton of Dalzell in 1990, inheriting land near and properties in the village of Betchworth in Surrey, and a Regency mansion. Political career Hamilton made his maiden speech in the House of Lords in April 1992. He was an impassioned and tenacious debater, even if no one else shared his views. Although a Conservative, he opposed his party on many issues (his family's Latin motto was "Quis occursabit" - "Who will oppose?") . He was a strong Eurosceptic, opposing his party on issues relating to the Common Agricultural Policy and on the Maastricht Treaty. With three other peers, he presented a petition to the Queen in 2001 under clause 61 of Magna Carta, a provision that had not been invoked for more than 300 years, claiming that the Nice Treaty breached Magna Carta. Unusually, perhaps, he supported a written constitution, which he saw as a means to inhibit
