In 1819 Wyndham succeeded his father, who was Member for Wiltshire, 1795-1812, to the bulk of an estate comprising land in Wiltshire and Hampshire, a medieval college in Salisbury and personal wealth sworn under £18,000.
He divided for production of the civil list revenue accounts, 3 May 1820, but was not listed as siding with opposition on any other motions for retrenchment and lower taxation in the early 1820s, and, indeed, voted against economies in revenue collection, 4 July 1820. He divided against censuring ministers’ conduct towards Queen Caroline, 6 Feb., disqualifying civil officers of the ordnance from voting in parliamentary elections, 12 Apr., and the forgery punishment mitigation bill, 23 May 1821. He was in majorities against abolishing one of the joint-postmasterships, 13 Mar., and inquiry into Irish tithes, 19 June 1822. In accordance with the mayor’s request, he forwarded to the corporation a copy of the petition from the inhabitants of Salisbury against the severity of Henry Hunt’s* gaol sentence, which was presented to the House by Benett, 24 Apr. 1822.
respecting the Catholic question, I assure you that my vote was not lightly given, nor until after the most mature deliberation on the important subject; for conscientiously differing from the opinion of many valued friends on this point, it demanded and received my most serious consideration; and the more I weighed the question in my mind, the more I felt convinced of the necessity of opposing the measure; for depend upon it, should the bill ever pass into a law, that sooner or later, consequences must arise that will endanger the safety of our present constitution.

His name headed the requisition for a local meeting on slavery, 1 Feb., when he supported a petition for its abolition, which he presented to the Commons, 9 Feb. 1826.
In giving thanks for his unopposed return at the general election of 1826, Wyndham trusted ‘that you will never have to accuse me of deviating from a manly independence, and that I shall ever evince an unshaken loyalty to my sovereign and a firm attachment to our excellent constitution’.
At the general election of 1830 Wyndham was returned with Duncombe Pleydell Bouverie, who was a reformer, like his brother Folkestone, now 3rd earl of Radnor. He entertained Princess Victoria to lunch on her visit to Salisbury in October that year.
that the question was one involved in difficulty; that he dared not think for himself on it; and that Sir Robert Peel was the person, above all others, in whose opinion he generally placed the highest confidence; and that he should probably be guided by him.

Wyndham, who informed a correspondent that ‘ministers are under some alarm, and by all accounts plunged into difficulty, by reason of their judicious measure and the excitement existing abroad’, believed that he had had the better of the argument. As expected, he was elected in second place, narrowly behind Pleydell Bouverie and, after rowdy scenes, he ‘got off as fast as he could, but did not escape being hustled’ in returning home.
He voted against the second reading of the reintroduced reform bill, 6 July, and for using the 1831 census to determine the boroughs in the disfranchisement schedules, 19 July 1831. He was listed as absent on the partial disfranchisement of Chippenham, 27 July. He divided in the majority against the second reading of the Irish union of parishes bill, 19 Aug. He voted against the passage of the reform bill, 21 Sept., and was named as a defaulter, 10 Oct., the day of Lord Ebrington’s confidence motion. He voted against the second reading of the revised bill, 17 Dec. 1831, the enfranchisement of Tower Hamlets, 28 Feb., and the third reading, 22 Mar. 1832. He attended the Commons on the resignation of the Grey cabinet, 9 May, and commented that ‘there is less fever in the House than could have been expected, and from the different speeches I calculate affairs will proceed in a quiet way’.
ministers were sadly put to shifts this morning at half-past three, and the only reason why they were not left in a minority on Herries’s motion was their friends observing they were so mauled and beaten down, that they did not afterwards wish to trample upon them, and quitted the House without voting.

Edward Hinxman of Little Durnford House wrote publicly to Wyndham, 21 June 1832:
Nothing could have been easier for you than to have followed that path, to have voted for a measure which in your conscience you believed dangerous to the country, and kept your seat in peace! But you pursued a nobler course, you sacrificed your interest to your principles.
Salisbury Jnl. 25 June 1832.
He was, in fact, re-elected at the general election of 1832 and, having been unseated in 1833, sat from 1835 until his death in October 1843. Remembered for his integrity and the strictness of his Conservative principles, the ‘unostentation in his generosity, sincerity in his friendships, true hospitality and a love of the invigorating sports of the field combined to make his character completely defined in the brief expression "a fine old English gentleman". He was succeeded by his sister Caroline Frances (?1769-1845), the wife of John Campbell (1771-1846) of Dunoon, Argyll and Blunham, Bedfordshire, and by their only son, John Henry Campbell (1798-1869) of Corhampton House, Hampshire, who was Member for Salisbury, 1843-7, and took the additional name of Wyndham in 1844.
