Nugent’s public career was effectively ended by the death of his uncle, the 1st marquess of Buckingham, in 1813, but he transferred his allegiance to the 2nd marquess, head of the Grenvillite faction, who returned him for his borough of Buckingham in 1818. The possessor of a sinecure governorship worth £109 a year, he unsuccessfully solicited the Irish command from the Liverpool ministry in 1819.
Buckingham returned him again at the 1826 general election, having told Fremantle that ‘he never attends, but I cannot break his old heart and refuse him the continuance of his seat as long as he chooses to twaddle with it’.
Living up to my income, and denying myself a great many comforts, which a man of my age, who has served long in unpleasant situations and bad climates, generally requires at the close of his life, I cannot meet any extra and unforeseen expenses ... Having given as large a portion to my daughter as I could well afford, there the expense and diminution of my income must end, in justice to my other children, as well as Lady Nugent’s and my own comforts.

The duke made him act as chaperone to Sir Thomas when he replaced William Fremantle as Member for Buckingham in May.
That summer he went with his wife to German and Swiss spas, before wintering at Naples. He left his affairs in the hands of Sir Thomas Fremantle, who managed by means of a lawsuit to recover some of the money owed by Norton.
After his return for Buckingham at the subsequent general election ministers counted him among their ‘friends’, and he was in their minority on the civil list, 15 Nov. 1830. On the 17th he presented a constituency petition for the abolition of slavery. At the end of 1830 he was prominent in organizing precautions at Marlow against further outbreaks of machine breaking, swearing in ‘a great number of special constables’ and seeking to ‘assemble a mounted constabulary force of 50 men’.
Nugent’s wife died in 1834; her perceptive journals of her experiences in Jamaica and India were posthumously and privately published in 1839.
