Martin, who became senior partner in the London banking firm of Martin, Stone and Foote in 1807, inherited his father’s property in Worcestershire three years later.
He was a regular attender who continued to vote with the Whig opposition to Lord Liverpool’s ministry on all major issues, including parliamentary reform, 9 Mar., 18 Apr., 9, 10, 31 May 1821, 25 Apr., 24 June 1822, 20 Feb., 24 Apr., 2 June 1823, 26 Feb. 1824, 13, 27 Apr., 26 May 1826. He divided for Catholic relief, 28 Feb. 1821, 1 Mar., 21 Apr., 10 May 1825. On 9 May 1820, during the debate on the motion for inquiry into the evidence against George Edwards, the government spy among the Cato Street conspirators, his adjournment motion was ‘immediately negatived’.
He divided against Hume’s call for further tax reductions, 3 Mar. 1823, explaining three days later that he thought the government had done ‘as much as could be done in the present circumstances of the country’, although he lamented the ‘state of inexplicable confusion’ in the public accounts.
Martin gave a ‘decided negative’ to the financial provision for the duke of Clarence, 16 Feb., voting against the annuity bill, 2, 16 Mar. 1827. He divided for Catholic relief, 6 Mar. He presented a Tewkesbury petition for retrenchment and reform, 8 Mar., and ones from Dissenters for repeal of the Test Acts, 25 May, 7 June.
He divided for Catholic emancipation, 6, 30 Mar., expressed ‘heartfelt pleasure’ at the ministry’s conduct, 9 Mar., and condemned the ‘inflammatory language’ used by peers, clergymen and magistrates in encouraging anti-Catholic demonstrations, 16 Mar. 1829. He voted to allow O’Connell to take his seat without swearing the oath of supremacy, 18 May. He thought ‘a reduction of our unfunded debt’ was ‘very desirable’, 11 May 1829. He voted to transfer East Retford’s seats to Birmingham, 11 Feb., 5 Mar. 1830, when he opposed voting by secret ballot as he did not believe it would ‘diminish bribery or corruption, or even intimidation’ and was ‘satisfied that a great moral good is effected when an individual comes forward boldly and openly ... and votes against what appears to be his pecuniary interest’; he voted against the disfranchisement bill, 15 Mar. He divided for Lord Blandford’s reform plan, 18 Feb., the enfranchisement of Birmingham, Leeds and Manchester, 23 Feb., and Russell’s reform motion, 28 May. He regularly voted with the revived Whig opposition that session on retrenchment motions. He had been unable to ‘make up my mind as to the propriety of ever abolishing the punishment of death’ in cases of forgery, 1 Apr., but concluded on 24 May that since the prospect of execution was deterring prosecutions, ‘we should try the experiment of a mitigated punishment’; he voted in that sense, 24 May, 7 June. He was ‘flattered at the honour’ of being asked to present a Worcester Catholics’ petition for Jewish emancipation, which was ‘a complete answer to the charges of bigotry and illiberality’ made against them, and voted accordingly, 17 May. He divided for reform of the civil government of Canada, 25 May, and of the divorce laws, 3 June, and repeal of the Irish Vestries Acts, 10 June. He voted to prohibit sales for on-consumption in beer houses, 21 June, and to delay it for two years, 1 July. He divided against the increased recognizances required of printers by the libel law amendment bill, 6, 9 July 1830. At the general election that summer he was again returned unopposed for Tewkesbury after assuring his constituents of his ‘abhorrence’ of slavery.
The ministry of course listed Martin among their ‘foes’, and he voted against them in the crucial civil list division, 15 Nov. 1830. He presented and ‘cordially advocated’ a Tewkesbury anti-slavery petition, 19 Nov. He supported the suspension of Evesham’s writ, as it was ‘one of the most corrupt boroughs in existence ... where the grossest bribery was carried on at every election’, 16 Dec. 1830. He warned that the proposed tax on the transfer of property would be ‘highly injurious to the public’ without greatly benefiting the exchequer and entered a ‘protest’ against the alternative suggestion of a property tax, 15 Feb. 1831. He expressed his ‘entire concurrence’ in the motion for inquiry into more efficient modes of secondary punishment, 17 Mar. That day he presented a Tewkesbury petition in favour of the Grey ministry’s reform bill, observing that ‘I approve of the measure not only for what it contains but also for what it does not, namely, a proposition for annual parliaments, vote by ballot and universal suffrage’. He divided for the second reading, 22 Mar., and against Gascoyne’s wrecking amendment, 19 Apr. 1831. At the ensuing general election he headed the poll at Tewkesbury as ‘the advocate ... of economy, retrenchment and reform, the enemy of colonial slavery, in whatever state and under whatever modification existing’, and as ‘the warm and devoted friend of civil and religious liberty’.
He drew attention to the ‘disgraceful state’ of Westminster Hall, 1 July 1831. He divided for the second reading of the reintroduced reform bill, 6 July, and generally supported its details, although he voted against the proposed division of counties, 11 Aug., and for the Chandos amendment to enfranchise £50 tenants-at-will, 18 Aug. He divided for the bill’s passage, 21 Sept., and Lord Ebrington’s confidence motion, 10 Oct. He voted to punish only those guilty of bribery at the Dublin election, 23 Aug. He voted to reduce the grant for civil list services, 18 July, and while supporting that for building work already done at Windsor Castle and Buckingham House, 28 Sept., he was ‘not ... prepared to vote ... any further sums’. He divided with the minority against the truck bill, 12 Sept. He was prevented by ‘severe illness’ from voting on the second reading of the revised reform bill, 17 Dec. 1831.
