Since 1780 the corporation nominee, Edward Coke of Longford, had joined interests with the 5th Duke of Devonshire, whose nomination to one seat at least was long established and who returned his brother. Both Members were Foxite Whigs, but neither voted for parliamentary reform in 1793, despite a petition from Derby in its favour (6 May). At the election of 1796 a local physician of means, Peter Crompton, standing as a reformer, made no impact against them, though he was said to have great influence on the corporation.
