‘A martyr to the rapacity and meanness of the Southampton Reformers’, Penleaze was ‘utterly ruined’ by his three election contests for the notoriously venal borough of Southampton, where he had first been returned as a reformer in 1831.
In 1819 Penleaze had inherited a substantial fortune from his surgeon father, whose origins are obscure. Ten years later he hemorrhaged a reputed £4,500 contesting a by-election at Southampton, where he had settled in the mid-1820s and become a senior member of the corporation. Defeated after a six-day poll, he spurned the 1830 election but in 1831 agreed to come forward as a supporter of the Grey ministry’s reform bill and was elected in second place.
At the 1832 general election he offered again, citing his loyal backing for the reform bill, regular attendance at Westminster and assistance in the construction of a local pier.
A fairly regular attender during his last stint in the Commons, Penleaze gave silent support in the lobbies to most radical causes, including the ballot, shorter parliaments, tax reductions, and lowering of the corn import duties. He was in the majority against Attwood’s motion for currency reform, 24 Apr. 1833, brought up constituency petitions against slavery, 18 Apr. 1833, and for the relief of Dissenters, 3 Mar. 1834, and divided steadily for opening universities to Nonconformists. Appointed to the Itchen bridge and roads committee, 21 Feb. 1834, Penleaze assumed the lead in guiding a bill to construct a floating bridge across the Itchen at Southampton Water into law, 25 July 1834, earning him plaudits from the local press for his ‘constant’ attendance.
Writing to the Whig lord chancellor Lord Brougham later that year for a living for one Rev. Ernest Hawkins, his son’s tutor, Penleaze described himself as a ‘staunch supporter of the present government’, adding that he ‘moderately advocated the diffusion of knowledge’ and believed in the ‘necessity of going along with, rather than being driven into, measures which the times require’.
In 1836 Penleaze was taken to court by Brooks’s for non-payment of his club subscription and postage costs, and ordered to pay £12 16s.
Penleaze returned to England to seek medical advice in December 1854, and after being advised to stay with a relative, died intestate at his son’s house in Hereford in April 1855. The Southampton lodge of Freemason’s, for whom he had acted as a provincial grand master in the early 1830s, paid him fulsome tribute.
