Cecil continued to sit for the pocket borough of Stamford on the interest of his elder brother the 2nd marquess of Exeter. At the 1820 general election he was returned unopposed in absentia, on account of ‘being out of health’.
At the 1830 general election he offered again for Stamford, where his brother’s control was challenged by Charles Tennyson, the independently minded former Member for Bletchingley. On the hustings, 30 July, he told an incredulous crowd, ‘I offer myself free and independent of party’, before pledging his support for the ministry. Under cross-examination, he denied that he had ‘acted injuriously to the poor’ and demanded that his opponents prove it. Challenged about his failure to support the beer bill, he claimed to have given it his backing. He repudiated the charge that unfair means were being used to secure his return, retorting that it was his opponents who were employing underhand tactics. He headed the poll throughout and at his victory dinner, 12 Aug., contended that ‘the electors of Stamford had been humbugged’ by Tennyson.
Cecil voted against the second reading of the reintroduced reform bill, 6 July, and its passage, 21 Sept. 1831. He divided against the third reading of the revised bill, 22 Mar., and paired against the second reading of the Irish measure, 25 May 1832.
Besides his excellent qualities, a good drill and a strict disciplinarian, he was a fine horseman, and a most forward rider in the hunting field. He rode in the first Grand Military steeplechase in Ireland when major of the regiment, and won the race, carrying the well-known Exeter colours.Liddell, 218.
Cecil died in November 1873. By his will, dated 19 Oct. 1871, he bequeathed to his wife all his personal property, £12,000 and the income derived from the residue of his estate. When his wife died in 1902, his great-great-nephew, William, 5th marquess of Exeter, inherited £62,614, the capital of his residuary estate.
