The scion of an ancient Buckinghamshire family, Chetwode was at a loss for a seat in Parliament. He was an admirer of Pitt and in 1790 sent him proposals for improving the tontine; in 1817 he was listed a Pitt Club member. He seems to have been in the running as a candidate for Denbigh in 1807, doubtless on the strength of his Cheshire connexions, but nothing came of it.
Within a year, Chetwode was Member for Newcastle-under-Lyme, under other auspices. His son-in-law Sir John Fenton Boughey was a Member for the borough, and when Lord Gower transferred to the county in 1815 Chetwode was induced by Boughey to offer on the independent interest there. His narrow victory in the ensuing contest deprived Lord Stafford of any say in the borough and provoked his revenge at the general election of 1818, when Chetwode stood down and his son-in-law was defeated by Stafford’s nominees.
In Parliament Chetwode is not known to have spoken. On 18 Mar. 1816 he was in the majority against the property tax. On 22 Mar. he took two weeks’ leave. He was in the government majorities on the civil list, 6 and 24 May 1816. He voted against Catholic relief that month and a year later. After leave of absence from 22 May, he joined opposition on the public revenue bill, 14, 17, 20 June 1816. In the session of 1817 he voted with government on the finance committee and Admiralty salaries, 7 and 17 Feb., against them for the reduction of the Admiralty Board, 25 Feb., and in favour of the suspension of habeas corpus, 23 May. He further voted with ministers on the conduct of the Scottish law officers, 10 Feb. 1818. He appeared in a government dining list that session, but his duties as a magistrate seem to have limited his attendance. On 29 May he dined with the Pitt Club. He was in the House on 1 June and next day requested his son’s future brother-in-law Edward John Littleton to lobby Lord Liverpool and Charles Arbuthnot on his behalf for a seat in the next Parliament.
