In March 1780, at the general election in September 1780, and again in 1784, Cotton was returned unopposed for Cheshire. He voted regularly with Opposition till the fall of North; for Shelburne’s peace preliminaries, 18 Feb. 1783; for parliamentary reform, 7 May 1783; and against Fox’s East India bill, 27 Nov. 1783. Robinson wrote of Cotton in his electoral survey of December 1783: ‘might perhaps without reckoning too much be classed pro’.
He died 24 Aug. 1809.
