Mackinnon, who had sat briefly before 1820, was spoken of as a local candidate for Southampton at that year’s general election, but declined to stand.
It has been suggested that Mr. Mackinnon’s return would be very acceptable to Sir Robert. Should this choice be confirmed, Sir H. would feel much pleasure in putting him in nomination.
Hants RO 27M74/F102, Neale to Peel [Apr. 1831].
Peel evidently approved and Mackinnon was returned unopposed for the borough, which lay some twelve miles from his residence.
He voted against the second reading of the Grey ministry’s reintroduced reform bill, 6 July 1831. On 19 July he moved an amendment for using the latest population figures to determine the disfranchisement schedules instead of the 1821 data, which would produce legislation based ‘on an ex post facto principle’. As he had anticipated, Lord John Russell replied that the 1821 census was more impartial than that gathered under the shadow of the reform bill, and his amendment was defeated by 224-169. He divided against the partial disfranchisement of Chippenham, 27 July, and considered it a ‘peculiar hardship’ that Lymington should also lose one Member, 29 July. He warned that political impartiality would be compromised by giving county sheriffs the right of selecting returning officers for some newly enfranchised boroughs, 10 Aug., and complained of having received no answer to this, 19 Aug. On 25 Aug. he opposed the introduction of a uniform borough franchise, noting that the ‘respectability’ of a £10 householder depended on the size of the town, and proposed to raise the minimum qualification to £15 in towns with between 500 and 1,000 houses and to £20 in those with more. Though negatived without a division, 26 Aug., his amendment received some verbal support, unlike his proposal that day to deny the vote to all tenants paying less than £20 per annum who sublet their houses, which he quietly withdrew. He voted against the issue of the Liverpool writ, 5 Sept., and presented a petition from London merchants against an increase in duty on Cape wine, 7 Sept. He divided against the third reading of the reform bill, 19 Sept., and its passage, 21 Sept. 1831.
Mackinnon voted against the second reading of the revised reform bill, 17 Dec. 1831, and going into committee on it, 26 Jan. 1832. Noting with approval the new bill’s adoption of most of his proposals on the census and appointment of returning officers, 3 Feb., he resubmitted his motion for a graded household qualification based on the size of towns, but without success; he did not redeem his promise to try again. He refuted assertions that signatures on a Hertfordshire anti-reform address had been obtained fraudulently, 10 Feb. On 23 Feb. he supported Chelmsford’s claim for inclusion in schedule C and, harking back to his contest at St. Ives, testified to its ‘thriving condition’, notwithstanding its position in schedule B. He divided against the enfranchisement of Tower Hamlets, 28 Feb. Speaking at length in terms reminiscent of his book, 20 Mar., he conceded the necessity of reform but denounced the bill as a product of ‘popular clamour’ rather than ‘public opinion’, objected to reducing the number of English and Welsh Members, and protested that the disfranchisement schedules and the criteria that determined them were destructive of the influence of property and wealth. His privately printed version of the speech concluded with a metaphoric vision of Parliament in flames, which was seized on by cartoonists.
Mackinnon supplied a point of information concerning the fees paid by Irish magistrates on renewal of their commissions, 17 Jan. 1832. He presented a petition for improving the laws against cruelty to animals, 20 Jan., introduced a bill to that effect, 18 Apr., and secured and was appointed to a select committee, 30 May. He presented their report, 1 Aug., but there was no time for the bill to progress further. (He subsequently revived it in the reformed House.) On 23 Jan. he denounced the Vestry Act amendment bill as an ‘attack on the church’ and complained that its provisions for broadening the franchise were ‘quite the prototype of the reform bill’, which would encourage ‘ever more popular measures, leading to universal suffrage and ballot’. He presented Marylebone petitions against the metropolis cemetery bill, 9 Apr., 8 May. That day he obtained leave to introduce a bill to reform the usury laws, which was given a first reading, 24 May, but lost out to other business thereafter. He voted against ministers on the Russian-Dutch loan, 26 Jan., 12 July 1832.
From a passage in his published speech on the reform bill, it is clear that Mackinnon expected to be returned for the reformed constituency of Lymington at the next general election. Writing in similar terms to Neale, 23 Oct., he observed that ‘the impression in my mind was that your influence was sufficient to retain a seat or to transfer it, and that you might give me the preference’, but in the event the patron had other ideas.
Mackinnon died intestate at Broadstairs in April 1870.
