Wyvill's cause was taken up by the Rockingham Whig opposition, culminating in the carrying of Dunning's motion in 1780. Some moderate reforms were implemented by the Rockingham-led administration of 1782. William Pitt the Younger raised a number of issues surrounding parliamentary reform in opposition to the Fox-North Coalition in 1783, but his proposal failed to gain the necessary support. In the wake of the French Revolution, Wyvill's platform came to be seen as moderate. Its influence can be detected in the later Great Reform Act and Chartist movement in the nineteenth century.
