His family’s readiness to foster dynastic alliances and clever manoeuvring by his grandfather Corbet and agents John Benyon and Charles Morgan had enabled Powell, like his great-uncle Thomas Powell (c.1701-52), to secure the county seat, the lord lieutenancy and the office of custos despite his heavy debts and evidence of rampant neglect on the scattered 30,000-acre Cardiganshire estates he had controlled since coming of age in 1809.
Powell, who made no reported Commons speeches before 1832, could spare little time for his parliamentary duties in 1820. His agents, Adam Armstrong of Ty’n rhyd and John Beynon of Newcastle Emlyn, and his solicitors Appleyard and John Hughes of Aberystwyth agreed that as an absentee who ‘neither understands nor takes the least interest in farming’, he should give up his loss-making home farm and let the mansion at Nanteos.
Powell divided against Catholic relief, 6 Mar. 1827. He received three weeks’ leave on urgent business, 10 Mar., and voted against the corn resolutions, 2 Apr. 1827. Drawing on his Aberystwyth assets over the next two years, he issued 60-year land leases for the construction of gentlemen’s houses in the Castle Field (Laura Place).
Ministers counted Powell among their ‘friends’ and he divided with them on the civil list when they were brought down, 15 Nov. 1830. He presented petitions for the abolition of colonial slavery from the Welsh Calvinistic Methodists of Aberaeron, Aberystwyth, Llanilar and Tregaron (where chapels had been built on his land), 25 Nov. 1830. He was granted three weeks’ leave, 14 Feb., and a further nine days, 8 Mar. 1831 because of illness, and so missed the early debates on the Grey ministry’s reform bill. Despite his previous reservations, he paired for it at its second reading, 22 Mar., so earning the approbation of the Cardiganshire reform meeting at Lampeter, 7 Apr. However, Kensington, who proposed the resolution of confidence in the sitting Members, made it known that he
would have been better pleased if I had seen the name of the Member for the county in another place, but, as I have seen his explanation I will only say, that I hope and trust and believe, or I would not do what I am now doing, that Mr. Powell will support the bill of Lord John Russell, not by pairing off, but by expressing his own, as well as the sentiments of his constituents in favour of it; and by voting for it in every stage. It is by that, that he will deserve the confidence and support of the county.
Powell voted against Gascoyne’s wrecking amendment, 19 Apr., presented Cardiganshire’s petition in favour of the bill, 20 Apr. 1831, and was not opposed at the general election that month.
He divided for the reintroduced reform bill at its second reading, 6 July, and, excluding his vote against the disfranchisement of Downton, 21 July, generally divided for its details. However, he failed to do so on the controversial amendments to award county votes to freeholders in cities corporate, 17 Aug., and to enfranchise £50 tenants-at-will, 18 Aug. He voted for the bill’s passage, 21 Sept., and received a month’s leave on the 30th to attend the sessions. He divided for the revised reform bill at its second reading, 17 Dec. 1831. He is not known to have voted for it subsequently, but he divided for the address asking the king to appoint only ministers who would carry it unimpaired, 10 May. He stayed away from Cardiganshire reform meetings but wrote to his constituents of his pleasure at giving them satisfaction by ‘my humble support for the bill’.
There was speculation in August 1832 that Powell might resign at the dissolution in favour of Herbert Evans’s stepson Delme Seymour Davies.
