Crompton, the son of a Derby banker, was brought in for East Retford in 1818 as Earl Fitzwilliam’s nominee and acted with the Whigs.
At the general election that summer Crompton stood for Derby, where Edward Strutt*, recognizing his superior pretensions, withdrew in his favour. Proud of being ‘unfettered by party’, he spoke on the hustings for free trade, the extension of liberties and the correction of abuses, but declared himself a cautious reformer, anxious to avoid ‘any rash change’. He was returned unopposed, with a member of the Cavendish family, and thereafter often presented petitions from his new constituents.
