Like his father, Downe followed the politics of Wentworth Woodhouse but, with no sure seat at his disposal, disappointed the 2nd Earl Fitzwilliam by climbing down when given every encouragement to become the Whig candidate for Yorkshire in 1788. He justified himself by saying that he was prepared to stand if Wilberforce’s illness caused a vacancy, but not to stand against Wilberforce at a dissolution, being a novice in electioneering.
Downe had joined Brooks’s Club on 12 June 1786 and the Whig Club on 6 Jan. 1787, a month before he entered Parliament. He supported opposition in silence before 1790 and his only known speech afterwards was as chairman of the Steyning election committee, when he presented the report, 7 Mar. 1791. There were doubts about his attitude to repeal of the Test Act in Scotland in 1791, but he further voted with opposition on Pitt’s foreign policy, 12 Apr. 1791, 1 Mar. 1792. Subsequently he was listed a Portland Whig (December 1792) and on 10 and 17 Feb. 1793 attended the meetings of Windham’s ‘third party’.
