Carter was born into the Whig oligarchy which dominated the corporation of Portsmouth, but was not the direct heir to his family’s local brewing and distilling concerns. He trained as a lawyer and by diligent practice in London and on the western circuit between 1819 and 1827 secured the financial independence which his inheritance had not provided (his father’s personalty had been sworn under £20,000 with no residue).
At the 1820 general election Carter offered again for Portsmouth, denying that he was a factious opponent of government and citing his approval of the suppression of blasphemous publications. He was returned at the head of a poll in which his family recovered control of the second seat.
In November 1825 Carter resolved to be more assiduous in keeping his journal of reflections on public affairs: ‘I am sure it will tend greatly to improve my mind ... I am conscious of a very slight and superficial knowledge of all things, even of those I ought to know thoroughly and I hope in some degree by these means to improve myself’. His good intentions evidently survived only a matter of days, though he wrote a brief record of his unopposed return for Portsmouth at the 1826 general election.
He argued against the rejection of a Leominster election petition on a technicality, 9 Feb., but was a teller for the minority against the acceptance of one from Dover, 13 Feb. 1827. He disagreed with Peel’s assertion that legislation to prevent bribery at elections should operate retrospectively, 26 Feb. He voted for Catholic relief, 6 Mar., when he was granted six weeks’ leave to attend the circuit. On the admission of Whigs to Canning’s ministry, Bonham Carter wrote to his colleague Francis Baring, 22 Apr.:
How do you feel when you hear of your contemporaries getting into public employments? I have no hesitation at saying that I should like exceedingly to be engaged in some office in which I could turn my talents to good account, but at the same time I am sure I should be very uneasy under the idea of service and a positive engagement to support my superiors through thick and thin.
Bonham Carter mss F12.
He informed his wife that he and Baring ‘shall not pledge ourselves to support the admin[istration] ... but I suppose we shall sit on the ministerial side of the House’, 30 Apr.
Bonham Carter admitted that a Portsmouth meeting against Catholic emancipation had been ‘conducted fairly’, but doubted the veracity of many of the signatures to its petition, 4 Mar. 1829. He ridiculed the attempt of Lord George Lennox to cast similar aspersions on a favourable petition from Portsmouth corporation, which he presented later that day, and brought up others in similar terms, 25, 27 Mar. He was, of course, expected by Planta, the Wellington ministry’s patronage secretary, to vote ‘with government’ on the issue and he divided accordingly, 6 Mar., though his name did not appear in any of the subsequent divisions. He voted for the transfer of East Retford’s seats to Birmingham, 5 May, and Lord Blandford’s resolutions in favour of parliamentary reform, 2 June 1829. Resuming his journal during the 1830 session, he explained that he had divided for Knatchbull’s amendment to the address, 4 Feb., ‘after much hesitation, because the language ... did not seem to me to go far enough in the description of the distress’. He voted for the transfer of East Retford’s seats to Birmingham, 11 Feb., 5 Mar., believing the case for disfranchisement to be stronger than that of Penryn. Despairing of ‘the silence of ministers’ on promised proposals, he voted for a general reduction in taxation, 15 Feb. He recorded that he voted twice for army reductions, 19 Feb., when he questioned the necessity of maintaining large British garrisons abroad, ‘or indeed that the colonies should be maintained’. He continued to divide steadily for military economies for the remainder of the session. He abstained from voting on Blandford’s parliamentary reform motion, as it contained ‘so many matters to which I was adverse’, 18 Feb., but he divided for the enfranchisement of Birmingham, Leeds and Manchester, 23 Feb. He voted for information on British military interference in Portugal, 10 Mar. As he privately doubted that any benefit would accrue, he did not support the referral of petitions complaining of distress to a committee of the whole House, 16 Mar., but he divided for inquiry into a revision of taxation, 25 Mar., ‘not being deterred by the apprehended consequence of a property tax’.
At the 1830 general election Bonham Carter, who was involved in the attempt to open the borough of Petersfield, was again returned unopposed for Portsmouth. On the hustings he welcomed repeal of the Test Acts and Catholic emancipation and predicted that parliamentary reform would shortly become a reality.
Bonham Carter was again returned unopposed at the ensuing general election, when he remarked on the irony that as old supporters of parliamentary reform, his close electorate would have ejected him had he not supported the measure. Afterwards he planned to travel to Cambridge to poll for the university reform candidates, and thence to Southampton, where he possessed a slight influence. At a meeting to promote the reform candidates for Hampshire, 25 Apr., he had wryly praised the lawyers who had volunteered their services, knowing only too well that they ‘seldom worked for nothing’. For his own part, he made an active canvass in the south of the county and contributed £108 towards the election expenses.
Bonham Carter’s eye for detail was evidently appreciated by Lord Althorp, who requested his assistance in redrawing the reform bill, 6 Nov. 1831.
At the 1832 general election Bonham Carter was returned at the head of the poll for Portsmouth on the widened franchise. According to William Cobbett†, who had visited the place in July 1832, he was ‘a great and general favourite of the people’ because, like his ancestors, he had so conducted himself ‘as to be ... beloved and respected’.
My father scarcely spoke in the House, and when speaking on the hustings, at meetings and elsewhere, he spoke tersely and to the point, without hesitation, but in rather a curt and severe style and without any attempt at oratory. His opinion on law questions was much looked up to and often asked in the House, where he was sure to give a straightforward decided answer which could be relied upon ... He frequently also would during a debate cross to the other side of the House and by quiet conversation and reasoning with individual Members, tend to bring the question in hand to a settlement much more than could have been done by an eloquent speech.
Bonham Carter mss F44.
In a similar vein his sister Hilary remarked in 1846 that their father’s career ‘was not a brilliant one, he was not eloquent, nor much admired nor followed after, but he was valued and trusted, and never found wanting, with a confidence that lives longer than a loud admiration’.
