Maxwell, whose family had been established at Pollok since the fourteenth century, joined Brooks’s Club, 10 May 1815, and was returned for Renfrewshire in 1818 as the nominee of the triumvirate of Whig families who controlled the county’s representation. He was praised by the 10th duke of Hamilton for the ‘Roman virtue that you determine to manifest in this corrupt age’, and was described by another Whig friend as having spoken in the House with the ‘free and unembarrassed air of a high bred gentleman’.
He was a regular attender and continued to vote with the Whig opposition to Lord Liverpool’s ministry on all major issues, including parliamentary reform, 9, 10 May 1821, 20 Feb., 24 Apr., 2 June 1823, 26 May 1826. He paired for Catholic relief, 28 Feb. 1821, divided against the Irish unlawful societies bill, 15 Feb., and voted for relief, 1 Mar., 21 Apr., 10 May 1825. He presented a petition from a ‘large number of distressed persons’ in Renfrewshire who lacked the means to emigrate, 19 May 1820.
He presented a Renfrewshire petition for relief from agricultural distress, 29 Apr., and argued that ‘all restrictions on the consumption of grain by prevention of distilling ought to be revised’, 7 May 1822.
He attended the Lanarkshire meeting on distress, 23 Sept. 1826, when he urged the need to ‘strike at the root of the evil’, as the ‘great mass of the inhabitants’ had been ‘reduced to a state of mendicity from the effects of war and misrule’, and everything should be done to help them even if it involved ‘trenching on the property of the county or the kingdom’.
He voted for the government’s Catholic emancipation bill, 6, 30 Mar. 1829, when he claimed that the Scottish people were ‘nearly divided upon it’, with the ‘lower classes’ being mostly hostile, whereas ‘the more intelligent’ were ‘happy to see the legislature following the lights of the age and spreading blessings over the kingdom’. He concurred with a friendly petition from Paisley, 7 Apr., that ‘the principles of the constitution are attacked’ by the Irish disfranchisement bill, on which he had not voted from ‘fear of having it used as a precedent in cases of future votes upon corrupt boroughs’. Nevertheless, he believed that Irish 40s. freeholds were a ‘great encouragement to those hovel establishments, which send out constant swarms of poor, uneducated labourers ... into England and Scotland’. That day he favoured referring petitions from the silk trade to a committee, observing that outside Parliament ‘there prevails the greatest possible disbelief of the advantages of the free trade system’. He presented a Renfrewshire freeholders’ petition for inquiry into distress, 7 May, but said he had refrained from submitting the desired motion for wage regulation because of the ‘strong feeling’ in the House against it. However, when presenting a Renfrewshire weavers’ petition for such regulation, 1 June, he announced that if no inquiry was granted he would move for one next session. He voted for a fixed duty on imported corn, 19 May. On 28 May he and the deputy advocate, Henry Home Drummond, introduced the Scottish landward parishes assessment bill, to give magistrates discretionary powers to vary the poor rate in certain districts, ‘so as to preserve the distinction between the local poor and the hordes who flock in upon them’. It permitted a higher rate of assessment to be imposed on ‘those bringing in [Irish] migrants’, who had spread the ‘same improvident spirit among the lower classes of the Scotch people’; his measure sought to ‘uphold those distinctions of character which it is ... important to maintain among the poor and the unfortunate’. The bill gained its second reading, 1 June, but made no further progress.
Maxwell offered for Lanarkshire at the general election in May 1831 as a supporter of the Grey ministry’s ‘great and efficacious’ reform bill. He maintained that ‘the people ... were entitled to the ... franchise from their education and intellectual capacities’, and was confident that reform would ‘strengthen’ the constitution. He was defeated by the Tory sitting Member after a riotous contest.
