A wealthy Durham landowner, Lambton became one of the county's MPs from 1813, advocating reforms and acquiring the nickname ‘Radical Jack’. He was created Baron Durham in 1828. When his father‐in‐law Grey became premier in 1830, Durham joined the cabinet and helped to draft the ministry's Reform Bill. He was promoted earl of Durham in 1834. From 1835 to 1837 he was ambassador to Russia. After a rebellion in Canada in 1838, he was sent there and produced the Durham Report. Although talented, he was difficult, proud, short‐tempered, and easily offended.
