Jesse Dickson Mabon PC FRSA (1 November 1925 – 10 April 2008), sometimes known as Dick Mabon, was a Scottish politician, physician and business executive. He was the founder of The Manifesto Group of Labour MPs, an alliance of moderate MPs who fought the perceived leftward drift of the Labour Party in the 1970s. He was a Labour Co-operative MP until October 1981, when he defected to the SDP. He lost his seat in 1983, and rejoined the Labour Party in 1991.
