Daniel Granville West, Baron Granville-West (17 March 1904 – 23 September 1984) was a British Labour politician. After establishing a successful solicitors practice, guided by Welsh baptist principles, he became a leading socialist in the post-war era. Baptised at the Tabernacle English Baptist Church, Monmouthshire, he remained a dedicated member all his life. Prominent in the opposition party during the Gaitskell period in 1950s and early 1960s, he remained committed to law and order in Wales, and nationalisation of the rail industry. He was horrified by the legacy of Imperial decline which he blamed for growing unemployment in the valleys.
