Townshend, a veteran of Waterloo, was again returned by his eldest brother Lord Sydney for the family borough at the 1820 general election.
At the 1826 general election Townshend made way for his nephew, but on the latter’s succession to the peerage early in 1831 he resumed the family seat. He voted against the second reading of the Grey ministry’s reform bill, by which Whitchurch stood to be completely disfranchised, 22 Mar., and for Gascoyne’s wrecking amendment, 19 Apr. At the ensuing general election he offered again as an opponent of the bill, which he described as an ‘infernal nuisance’, and was returned unopposed.
If I for a moment thought that the ... [bill] was likely to be attended with advantage to my country, I would be among the foremost ranks in its support. But as, on the contrary, I conceive it to be fraught with danger and mischief to our constitution, I shall ever, with heart and hand, give my assistance in preventing it being made one of the laws of the land.
He divided against some of its details, 27 July, 2 Sept., and its passage, 21 Sept. He paired with the minority of diehards opposed to the Maynooth grant, 26 Sept. He voted against the second reading of the revised reform bill, 17 Dec. 1831, and was in the minorities against going into committee on it, 20 Jan., the enfranchisement of Tower Hamlets, 28 Feb., and the third reading, 22 Mar. 1832. He voted against the second reading of the Irish measure, 25 May. He divided against ministers on the Russian-Dutch loan, 26 Jan., but was in their majority against inquiry into military punishments, 16 Feb. He was in the minority of 17 against the malt drawback bill, 29 Feb. 1832. His parliamentary career ended with the disfranchisement of Whitchurch.
Townshend died unmarried at his home in Bolton Street, Piccadilly, in May 1843. By his will, dated 3 Apr. 1843, he left bequests of about £22,000, including £5,000 to his sister Lady Dynevor, £5,000 to each of his godchildren Lady Harriet Janet Sarah Moore and the Rev. Edward Moore, and £5,000 to his niece, Harriet Lucy Rice. His personal estate was sworn under £60,000. The residue passed to his nephew and executor Lord Sydney. At his request his burial pall was dressed in the ceremonial colours of the Grenadiers and his coffin carried to the family vault at Chislehurst by regimental survivors of Waterloo.
