"Jones, Britain’s best-known left-wing commentator, was born in Sheffield in 1984. His parents, both members of the Militant Tendency, met while canvassing for Labour in the late sixties; his father was a trade-union shop steward, his mother a prominent computer-science academic. Other relatives were Labour councillors and radical preachers ... After reading history at Oxford and a stint as a trade-union lobbyist he worked for two British left grandees: archiving the papers of Eric Hobsbawm, and serving as a parliamentary researcher to John McDonnell."
